Week 3

This past week in Pre Calculus we finished unit 1-Sequences and Series and then we started unit 2-Absolute Value and Radicals. We learned what absolute value was and what the symbol to represent it looks like.

Absolute value is the distance of any number to 0. Example is 4 is 4 numbers away from 0 so it would be written as \mid4\mid .

If the number is negative like \mid-4\mid it must be changed to a positive to \mid4\mid .
