A New and Original PEMDAS Mnemonic by Debbie Adeoti 9.2

This Math Project shows a brand new and orginal mnemonic for the order of operations:

P earl = Parentheses

E arrings= Exponents

M ake= Multiplication

D ad= Divison

A lways= Addition

S mile = Subtraction

Now let's put this mnemonic into effect:

Evaluate 3 + 6 x (5 + 4) ÷ 3 - 7 using the order of operations.

Solution:

Step 1: 3 + 6 x (5 + 4) ÷ 3 - 7 = 3 + 6 x 9 ÷ 3 - 7 Parentheses

Step 2: 3 + 6 x 9 ÷ 3 - 7 = 3 + 54 ÷ 3 - 7 Multiplication

Step 3: 3 + 54 ÷ 3 - 7 = 3 + 18 - 7 Division

Step 4: 3 + 18 - 7 = 21 - 7 Addition

Step 5: 21 - 7 = 14 Subtraction
