Order of Operations 2021

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The common acronym used is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS stands for: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

What is the first step in solving the expression: 6 + (2 × 3)?

Back

The first step is to solve the expression inside the parentheses: (2 × 3) = 6.

Front

In the expression 5 - 3 + 2, which operation should be performed first?

Back

Subtraction should be performed first, so 5 - 3 = 2.

Front

Calculate: (9 + 23) ÷ (5 - 3)

Back

(9 + 23) ÷ (5 - 3) = 32 ÷ 2 = 16.

Front

What is the result of 14 + (22 - 2)?

Back

14 + (22 - 2) = 14 + 20 = 34.

Front

In the expression 4 + 9 + 8 ÷ 4, which operation is performed last?

Back

Addition is performed last. The correct order is to first divide 8 ÷ 4 = 2, then add: 4 + 9 + 2 = 15.

Front

What is the value of 6 × 7 + (9 - 3) + 2?

Back

First, calculate (9 - 3) = 6, then 6 × 7 = 42, and finally 42 + 6 + 2 = 50.

Front

What is the error in the calculation: 5 - 3 + 2 = 5 - 5 = 0?

Back

The error is that addition was done first instead of subtraction. The correct order is to subtract first.

Front

What is the result of 8 ÷ 4 + 3 × 2?

Back

First, divide: 8 ÷ 4 = 2, then multiply: 3 × 2 = 6, and finally add: 2 + 6 = 8.
