Here's a handy process you can use to be sure you are rounding correctly.
Whatever number you have, underline the place value that you need to round to:
1,354,029
Everything to the right of that number will turn into 0's. The trick is:
Will you bump up the 4 or just dump the rest...
The order of operations always applies in equations. I like to remember the order of operations as:
Please Excuse MyDear AuntSally or Parentheses (Grouping Symbols), Exponents, Multiply/Divide left to right, and finally Add/Subtract left to right.
It appears in your problem that there are...
Hi Alaina,
In elementary school, we learn various ways to solve problems, but mostly we are learning the basics of computation or arithmetic. I like to think of algebra as being a detective to find a mystery number, which instead of having a box or shaded area, now
uses a letter.
So,...
Hi Jesse,
If you follow a couple of simple rules of algebra, you won't have to worry about the denominators.
First, what you do to one side of the equation, you MUST do to the other side in order to keep it balanced.
Second, you need to get all of the terms that go together on one side...

Before you can combine like terms, you must always first consider if you need to use a number manipulation property, like the commutative, associative, or distributive property. Then you need to check if the order of operations is the next step in working
through the problem. Combining like terms...
You can find common factors by comparing the factors of 2 different numbers, like 12 and 20. You can determine common factors in 2 way: either making a list of the factors of both numbers or by finding the prime factors of both of them. Both methods are
useful, but for smaller numbers, memorizing...
Hi Riley,
If you put money in the cash box to start in order to make change, then that money was not part of the profits and must be subtracted out at the end of the day. In this problem The $453.50 is made up of the $25 starter money AND the amount that was taken
in. To solve, subtract $25...
Think of it tihs way:
If you have 15 / 3, you have 15 things and you are putting 3 things in a group. If you divide it this way, you will get 5 groups.
If you have 15 / 1, you have 15 things and you are putting only 1 thing in a group. If you divide it this way, you will get 15 groups.
If...
