Teach your class about the additive inverse! Using examples first and a definition second, this video explains what the additive inverse it and how to find the additive inverse of any given number or variable. A quick concept review for...

Subtract polynomials? Huh? First off find the additive inverse of the number you are subtracting. Next rewrite the polynomials one on top of the other. Make sure to line up the like terms and then write in placeholders. Now add the terms...

Finding the additive inverse is not as complicated as you might think. The instructor demonstrates how to multiply each of the terms in the polynomial by -1 and explains how this works. But wait, there's a quicker way. What's that you...

The instructor demonstrates that when you add the opposite value of a given number to that number you will always get zero. Then she shows how multiplying by the inverse of any number except zero will equal 1.
