Intro to Order of operations

Front

What is the Order of Operations?

Back

A set of rules that determines the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does PEMDAS stand for?

Back

PEMDAS is an acronym that stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which is the order in which operations should be performed.

What is the first step in solving (12 + 10) ÷ 10 · 14 - 6?

Back

The first step is to perform the operation inside the parentheses: 12 + 10 = 22.

Front

In the expression 20 - 5 x 2, which operation do you perform first?

Back

You perform multiplication first: 5 x 2 = 10.

Front

What is the second step in solving (4 - 2) + 9 x 7?

Back

The second step is to perform the multiplication: 9 x 7 = 63.

Front

What is the first step in solving 3 + 4 x 6 - 4?

Back

The first step is to perform multiplication: 4 x 6 = 24.

Front

What is the first step in solving (3 + 4) 9 + 3?

Back

The first step is to perform the operation inside the parentheses: 3 + 4 = 7.

Front

What is the result of 5 + 3 x 2?

Back

The result is 11, because you perform multiplication first: 3 x 2 = 6, then add 5.

Front

What is the result of (8 - 3) + 2 x 5?

Back

The result is 10, because you perform the operation in parentheses first: 8 - 3 = 5, then 5 + 10 = 10.

Front

What is the result of 6 + 2 x (3 + 1)?

Back

The result is 14, because you perform the operation in parentheses first: 3 + 1 = 4, then 2 x 4 = 8, and finally 6 + 8 = 14.
