Order of Operations

Front

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

What is the first step in the order of operations?

Back

The first step is to solve expressions inside Parentheses.

Front

In the expression 5 + 2 × 3, which operation do you perform first?

Back

You perform multiplication first, so 2 × 3 = 6, then add 5 to get 11.

Front

Back

The value is 11, because you multiply 4 × 2 first to get 8, then add 3.

Front

Back

You perform the operations from left to right, so you subtract 2 from 8 first to get 6, then add 5 to get 11.

Front

Back

The value is 6, because you divide 6 by 2 first to get 3, then add 3.

Front

Back

You perform the exponentiation first, so 2^3 = 8, then multiply by 4 to get 32.

Front

Back

The value is 8, because you calculate 3^2 first to get 9, then 10 - 9 + 1 = 2.

Front

What is the order of operations?

Back

The order of operations is the rules that define the correct sequence to evaluate a mathematical expression.

Front

Back

You perform the exponentiation first, so 10^3 = 1000.
