PEMDAS youtube video

PEMDAS in action

Here is an example of PEMDAS in action

3 * ( 5 + 8 ) - 2² / 4 + 3

Parenthesis first: 5 + 8 = 13

3 * 13 - 22 / 4 + 3

Exponent next: square the 2 or 2² = 4

3 * 13 - 4 / 4 + 3

Multiplication and Division next (3 * 13) (4 / 4)
left to right:

39 - 1 + 3

Addition and Subtraction next
left to right:

39 - 1 + 3 = 41

Note that we first subtracted 1 from 39 (left to right!),
then added the 3 for the correct answer, 41.

This week in math...

This week we are covering order of operations in math. Students have been given the acronym of PEMDAS. Which stand for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. This gives students the ability to "attack" the equation.
