Willpower is unique to humanity. It is the keystone characteristic that is directly responsible for our technological advancement over the last several hundred thousand years. Willpower can be defined as the capacity to restrain our impulses and resist
temptation in order to maximize our long-term success. It is the expulsion of energy to fight off innate survival based urges to exponentially increase future advantages and benefits. It is the driving force behind all civilizations, and it is what prods humankind
forward to learn and grow.
When we turn down a bite of cheesecake, step away from a mind numbing reality sitcom, or push off a nap to get some work done, the credit goes to willpower. It is this ghost like aura of control and discipline that we rely on to extend our existence and maximize
our accomplishments. When we watch highly successful individuals exercise routinely, read voraciously, and work tirelessly, we are impressed with their ability to resist...

MP3 players example
The profit in millions of dollars for an MP3 player can be done with the polynomial P=-4x^3 + 12X^2 + 16X. X represents the number of MP3 players produced annually. The company currently produces 3 million MP3 players and makes a profit of $ 48,000,000.
To figure out the least amount of MP3 players the company can produce and still make the same profit we need to solve for P.
Step 1
Set P=48 This represents the total profit. 48=-4X^3 + 12X^2 + 16X
Step 2 subtract the 48 from 48 and from the end of the equation, like this 48=-4X^3 + 12X^2 + 16X - 48

After several months of carrying some pretty heavy textbooks around with me, I recently decided to switch to a Kindle Fire and start using electronic textbooks. Although there are times when a good old-fashioned book really cannot be replaced, I'm very
pleased with the weight of my tutoring bag now, and my students seem to be enjoying the switch as well.
I'm able to download textbooks for free in some cases ("Boundless" publishing), and I also have several different dictionaries and other reference books a tap away! Any other books I might find helpful for my students? Just a few clicks away. This also
frees up my paper textbooks to loan to my students in-between sessions.
Using a Kindle gives me the added benefit of being able to load educational applications to use for practice and reinforcement. Since we are in the 'computer testing' age, this also gives my students some extra practice in preparing for computerized exams.
I'm sure you'll...

When a young person takes their first higher math course, Algebra I, their brains are developing a different set of skills than arithmetic, and they are faced with abstract concepts. Most students are intellectually ready for this transition in the 8th
or 9th grade. Many students have to be patient, I as it sometimes takes a few months for the "aha" moment when it all clicks. I find that their are many ways to teach algebraic concepts that allow students to grasp the particular skill they are working on.
I use methods such as real-world examples, I foldable study guides, reviewing or introducing basic concepts such as inverses and identities, using colors, using hands-on materials like algebra tiles, and more. I often have students use highlighters or make
their own problems. After 28 years of teaching, I know which misconceptions are made most often, so I also what NOT to do and why. Research has repeatedly shown that success in Algebra II is the best predictor...

Come with me on a journey of division.
I have here a bag of M&Ms, which you and I and two of your friends want to share equally. I'm going to pour the bag out on the table and split it into four equal piles. For this example, “one bag” is our whole, and the best number to represent that whole would
be the number of M&Ms in the bag. Let's say there were 32. If I split those 32 M&Ms into four equal piles and asked you how many were in one pile, you could certainly just count them. But a quicker way would be to take that 32 and divide it by the number of
piles I'd made, which in this case is 4. You'd probably write that as:
32 ÷ 4 = 8
So there are 8 candies in each pile.
Seems easy enough with a large number of M&Ms, right? But what if there were less candies – what if our “whole” was less than the entire bag? Well, for a while we'd be okay – if there were 16, for example, we'd do the same thing and come up with piles of 4
instead...

"I can't do this. Why do I need to know this anyway? Can't we just use the computer to do this?"
We have all heard this from someone; ourselves, our spouses, friends and all too often we hear this from our children.
We have seen math as a difficult subject for our generation and now we are seeing math become even more "frustrating", "boring", and "intimidating" for many of our children. We have tried collaboration, individual tutoring and even extra home work as a
means toward improvement. But many of our efforts are met with failure, anger and even tears. What is the key to overcoming the math "Mount Everest"? While there is no band aid for healing math confusion, there are tips and strategies that are fundamental
in changing your child's view of math and developing "number sense".

Hello everyone,
One of my Calculus students had an interesting Related Rates problem that I had to go home and think about for a while in order to figure out. The problem was set up as such:
A 25 inch piece of rope needs to be cut into 2 pieces to form a square and a circle. How should the rope be cut so that the combined surface area of the circle and square is as small as possible?
Here's what we'll need to do:
1. We will have to form equations that relate the length of the perimeter and circumference to the combined surface area.
2. We will then differentiate to create an equation with the derivative of the surface area with respect to lengths of rope.
3. Wherever this derivative equals 0 there will be a maxima or minima, and so we will set the derivative = to 0 and determine which critical points are minima...

In this video, elementary algebra is built up from counting to positive numbers to negative numbers to multiplication and division to exponents and logarithms. All these concepts are tied together under the common theme of "fancy counting." That is, each
of these operations is tied directly to the fundamental operation of "+1".
All of this in just over 9 minutes. This is how experts think of algebra. Novices, new to the world of algebra, see the mechanical steps to be taken, the shuffling of symbols, the confusing mass of numbers, letters, and symbols and get lost. Experts think
of algebra as chunks of value that are being operated upon by a (relatively) small set of operations, made smaller by lumping an operation with its inverse (addition/subtraction, multiplication/division, exponents/logarithms) and realizing they are two sides
of the same coin.
"How I Feel About Logarithms,...

One of the common questions I get asked when I am tutoring algebra is how to find the difference of squares. First, what exactly is a difference of squares, and what is it used for? Second, how do you find it?
The difference of squares is a tool used to factor certain types of polynomials. Factoring is often useful in simplifying equations and allow some form of cancellation or combination of like factors. The difference of squares will allow you to factor some polynomial
types that are not otherwise factorable, making it a useful tool in algebra and anything that uses algebra.
So how do you find it? You can find the difference of squares for any polynomials which is a difference of two perfect squares. Take the simplest case: x2 -1. This polynomial is the difference of two perfect squares: x2 is, obviously,
the square of x while 1 is the square of 1. The resulting factors, using the difference of squares, is (x+1)(x-1).
To confirm that this...

I find oftentimes that one of the biggest stumbling blocks for algebra students is that beginners have difficulty seeing the "chunks" in an expression. Instead, they see a big jumbled mess of symbols.
An analogy is an orchestra. A person who has never played a musical instrument, or doesn't have much experience with listening to music, hears the orchestra as one big sound. The trumpets, flutes, strings, percussion all happening at once.
An experienced musician can isolate each instrument, and let the rest of the orchestra fade, focusing on the single melody or harmony line.
Likewise, an experienced mathematician can isolate the sections of an expression, focusing on the single term or operation that needs to be dealt with at the moment, allowing the rest of the expression to fade away for the time being, until the term or
operation has been dealt with.
Consider the following problem; can you see...

I recently responded to a question on WyzAnt's “Answers” page from a very frustrated student asking why he should bother learning algebra. He wanted to know when he would ever need to use it in the “real world” because it was frustrating him to tears and
“I'm tired of trying to find your x algebra, and I don't care y either!!!”
Now, despite that being a pretty awesome joke, I really felt for this kid. I hear this sort of complaint a lot from students who desperately want to just throw in the towel and skip math completely. But what bothered me even more were the responses already
given by three or four other tutors. They were all valid points talking about life skills that require math, such as paying bills, applying for loans, etc., or else career fields that involve math such as computer science and physics. I hear these responses
a lot too, and what bothers me is that those answers are clearly not what this poor student needed to hear. When you're that frustrated...

I used to do this and I see a lot of students who do this common mistake when studying. Maybe you are working through old homework problems to prepare for an exam in math or physics and you have the solutions in front of you. You get to a certain point
and you get stuck, so you check the solution, see what the next action you have to take is, and then continue working through the problem. Eventually you get an answer that may (or may not) be right and check the solution again. If it is, you feel great and
move on. If it isn't you compare the work and see what you did wrong and understand the mistake so you move on. All this is a fine way to start studying, but the major mistake is that most students don't go back to that problem and try to do it again. Even
if you were able to understand the solution or the mistake you made, you never actually got through the problem completely without aid. So now if you come to this problem on your test, this will be the first time you actually...

I've heard this sentiment over and over--sometimes from students, and sometimes, I'll admit, in my own head.
Last night, I was working on my own math homework, and there was one problem I just couldn't get my head around. I read the book, looked back at my class notes, and even sat down with a tutor for a while, and still, when I tried a new problem of the same type
on my own, it just didn't work!
"Maybe I'm not as good at math as I thought," I told myself. "Am I REALLY smart enough for bioengineering?"
It was hard, but I told myself "YES!" And I kept working. I laid the assigned problems aside and started doing other problems of the same type from the book. I checked my work every time. Each problem took at least ten minutes to solve, and the first three
were ALL wrong! I kept going. I got one right, and it made sense! I did another, and it was half right, but there was still a problem. I did another, and it was right...

Algebra does us the favor of assigning numbers to cause-and-effect relationships.
For instance, we sense that exercise leads to weight loss.
Algebra answers that key question: "How much?"
Difficulties come in three forms: expressions that mix numbers with letters, minus signs, and fractions.
COPING STRATEGIES
View equations as balance scales or "seesaws": (+)weights point down, (-)wts point up, with "=" as the pivot.
Vocalize equations like a "recipe": 2x-7 = 9 is "double the 'x' and remove '7' to make '9'."
Use "containers" instead of letters: "x" is a box and "y" is a bowl. What's in the box for "box +box -7 = 9?"
Move "minus" elements "to the other side." What's in the box for "box +box = 9 +7?"
Re-scale to get rid of denominators: x/2 - x/6 = 8/3 becomes...

One of the common challenges for many Algebra students is forgetting important concepts from Pre-Algebra. So many students complain that they never fully learned fractions, decimals and percentages or ratios, rates and applying math to word problems. Without
solid memorization of multiplication & division tables, factoring and simplifying are much more difficult. A better understanding of the basics, including learning different methods and shortcuts, can not only boost confidence but can improve grades and SAT
scores.
Spend time with a tutor or use different websites to review topics from previous years. It will help, exponentially!

You have a science paper due on Monday. History test and math packet due on Tuesday. English project group meeting Wednesday after school. Homework to complete. Chores on Saturday. And you want to spend time with a friend.
Use a student planner.
Be specific with the time. Include day/date and time/hour. Specifying the hour in your planner creates an actual appointment, and appointments are not made to be broken.
During the week, your friend calls, wanting to come over and watch a movie with you on Saturday at 1:00 pm. You look at your planner. It shows you will be completing your history reading assignment at that time; you suggest 3:00 pm to your friend.
It’s Saturday, 3:00 pm. Your friend knocks at the door.
What’s that? You say you’re feeling great, relaxed, at ease. Oh yes. That’s part of the reward of scheduling, and sticking to it. You've read and studied the chapter for your history class. You finished your chores. Now you can really enjoy a movie.

Are you having some difficulties with your math or science class? Many students have this feeling at some point during the semester. Unfortunately, most of them think that the new chapter will be starting soon and then everything will be ok. While this might
be the case, math and science are two subjects where the material builds from chapter to chapter. Missing a key formula or concept in one chapter can really affect how the rest of the semester goes.
So don't wait too long to get some help. Maybe all you need is one or two sessions with a tutor to clear up a concept. Hiring a tutor doesn't have to be a long term commitment. But if it turns out that more help is necessary, you've made a great decision
in starting early. Remember, it is better to have a tutoring session early and clear up any misconceptions than to feel like you need to learn a whole semester of material in a day or two before the final.
