Order of Operations - 6th

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 acronym PEMDAS helps remember the order: 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

Calculate: 5 + 2 × 3

Back

5 + 2 × 3 = 5 + 6 = 11 (Multiplication first, then addition).

Front

Calculate: (4 + 6) ÷ 2

Back

(4 + 6) ÷ 2 = 10 ÷ 2 = 5 (Parentheses first, then division).

Front

What is an exponent?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, 3² means 3 × 3.

Front

Write 5 x 5 x 5 using an exponent.

Back

5 x 5 x 5 = 5³.

Front

Calculate: 8 - 3 + 2

Back

8 - 3 + 2 = 5 + 2 = 7 (Subtraction first, then addition).

Front

Which operation do you perform first in: 6 + (2 × 3)?

Back

You perform the multiplication first: 2 × 3 = 6, then 6 + 6 = 12.

Front

Calculate: 12 ÷ 4 + 5

Back

12 ÷ 4 + 5 = 3 + 5 = 8 (Division first, then addition).

Front

What is the result of: 2 + 3 × 4 - 5?

Back

2 + 3 × 4 - 5 = 2 + 12 - 5 = 9 (Multiplication first, then addition and subtraction).
