Order of Operations : 

Order of Operations By John Latchett

Order of OperationsSequence of Steps : 

Order of OperationsSequence of Steps P - Parenthesis E - Exponents M - Multiplication D - Division A - Addition S - Subtraction

Remember!!!! : 

Remember!!!! Multiplication and Division are solved left to right in a problem. Addition and Subtraction are solved left to right in a problem.

Examples of Solving Equations : 

Examples of Solving Equations 9 x (20 – 18) + 25 ÷ 5 = 1st step (P) - (20 – 18) = 2 Re-Write Problem: 9 x 2 + 25 ÷ 5 = 2nd Step (M) 9 x 2 = 18 Re-Write Problem: 18 + 25 ÷ 5 = 3rd Step (D) 25 ÷ 5 = 5 Re-Write Problem: 18 + 5 = 4th Step (A) 18 + 5 = 23 Answer = 23

Examples of Solving Equations : 

Examples of Solving Equations 10² + 5 x (45 + 5) ÷ 5 = 1st step (P) - (45 + 5) = 50 Re-Write Problem: 10² + 5 X 50 ÷ 5= 2nd Step (E) - 10² = 100 Re-Write Problem: 100 + 5 X 50 ÷ 5 3rd Step (M) - 5 X 50 = 250 Re-Write Problem: 100 + 250 ÷ 5 4th Step (D) - 250 ÷ 5 = 50 Re-Write Problem: 100 + 50 5th Step (A) – 100 + 50 = 50 Answer = 50

Remember Order Sequence!!! : 

Remember Order Sequence!!! P - Parenthesis E - Exponents M - Multiplication D - Division A - Addition S - Subtraction
