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 and Division (from left to right), Addition and Subtraction (from left to right).

Front

Evaluate: 2 + 3 x 4

Back

14 (First, multiply 3 x 4 = 12, then add 2 = 14).

Front

Evaluate: (5 + 3) x 2

Back

16 (First, add 5 + 3 = 8, then multiply by 2 = 16).

Front

What is the base in an exponent?

Back

In the expression 3^4, the base is 3. It is the number that is multiplied by itself.

Front

What is the exponent in an exponent?

Back

In the expression 3^4, the exponent is 4. It indicates how many times the base (3) is multiplied by itself.

Front

Evaluate: 6 + 2^3

Back

14 (First, calculate 2^3 = 8, then add 6 = 14).

Front

Evaluate: 10 - (2 + 3) x 2

Back

0 (First, calculate (2 + 3) = 5, then multiply by 2 = 10, and finally subtract 10 - 10 = 0).

Front

Evaluate: 4 x (3 + 2) - 5 x 4

Back

0 (First, calculate (3 + 2) = 5, then 4 x 5 = 20, and 5 x 4 = 20, finally 20 - 20 = 0).

Front

True or False: 2 x 3 + 10 ÷ 2 = 8

Back

False (The correct calculation is 2 x 3 = 6, 10 ÷ 2 = 5, then 6 + 5 = 11).
