Order of Operations: BPEMDAS

Step-by-step explanation:

We must follow BPEMDAS rules.

We first look at the parenthesis, and evaluate it left to right. In the parenthesis, the first order of higher operation would be division, hence B is our answer.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
