Hi Courtney!  I see that you have an equation of -4y-(5y+6)=-7y+3.  Here's how you solve it: 1.  Use the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). 2.  Ask yourself about each of these operations to show your work...

Here's a sample addition problem of 2 2-digit numbers:        36 + 48      Referring to that problem above, on a piece of paper, I would make 6 and 8 dots for the place value of ones and 3 and 4 vertical lines for the place value of tens.  This would help any kid understand the structure of each number so that he or she... read more

Well, there are two exceptions to this question. X cannot be 0 or 1 because 0*0=0, and 1*1=1. No matter how many times you multiply 0 by itself, you will always get 0, and no matter how many times you multiply 1 by itself, you will always get 1. That's why the power of x will never change its value if x is 0 or 1. Now that we realize the two exceptions of 0 and 1 for x, x would have to be in... read more

The fraction 15/17 means that a whole is divided into 17 equal parts according to the denominator, and only 15 of those 17 equal parts are seen according to the numerator.  Since the numerator 15 is smaller than the denominator 17, that means 15/17 is a proper fraction.  Now, if all...

How to add or subtract fractions: 1.  Look at the denominators.  Are they the same or are they different? 2.  If they are different, then that means each fraction is divided into different numbers of equal parts -- so different that you won't know how many equal parts you...
