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 Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It is the order in which operations should be performed in a mathematical expression.

Front

Calculate: 3 + 5 x 2

Back

3 + 5 x 2 = 3 + 10 = 13 (Multiplication first, then addition).

Front

Calculate: (4 + 6) x 2

Back

(4 + 6) x 2 = 10 x 2 = 20 (Parentheses first).

Front

What is the GCF (Greatest Common Factor) of 32 and 40?

Back

The GCF of 32 and 40 is 8.

Front

What is the LCM (Least Common Multiple) of 10 and 6?

Back

The LCM of 10 and 6 is 30.

Front

Calculate: 2^3 + 4

Back

2^3 + 4 = 8 + 4 = 12 (Exponents first, then addition).

Front

What is an exponent?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, 2^3 means 2 x 2 x 2.

Front

Calculate: 7 x 7 x 7 x 7 x 7 x 7

Back

7 x 7 x 7 x 7 x 7 x 7 = 7^6.
