This week we learned about:

-Absolute Values

– Roots

– Radicals

Absolute values

We learned this week what absolute values are and how to properly go about them. Anything inside the absolute value “bracket” will always end up being positive. For example: |12 – 15 | = +3

Make sure you always do all the calculations before you turn the answer positive.

Roots and Radicals: 

We learned the terms this week. The number in front the square root sign is the coefficient, the small number connected to the square root is the index and the number inside is called the radicand. We learned that the index is a very important clue for the equations because it tells us is the number in the radicand spot can me both negative and positive or only positive. Even number index can only be positive while uneven index can be either. Also simplifying equations, the index is important because it tells us what we can take out to become the coefficient. if the index is 2 we take groups of two.
