Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression.

Front

What does PEMDAS stand for?

Back

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

Front

What operation do you perform first in the expression: (3 + 5) × 2?

Back

You perform the addition inside the parentheses first.

Front

In the expression 8 + 2 × 5, which operation is performed first?

Back

Multiplication is performed first, so 2 × 5 = 10.

Front

Evaluate the expression: 4 + 6 ÷ 2.

Back

4 + 3 = 7.

Front

What is the result of the expression: 10 - 3 + 2?

Back

The result is 9, as subtraction and addition are performed from left to right.

Front

In the expression 12 ÷ (2 + 4), what do you calculate first?

Back

You calculate the expression inside the parentheses first, so 2 + 4 = 6.

Front

What is the value of the expression: 5 × (3 + 2) - 4?

Back

The value is 21, as you first calculate inside the parentheses, then multiply, and finally subtract.

Front

If you have the expression 15 - 3 × 2, what is the first operation?

Back

The first operation is multiplication: 3 × 2 = 6.

Front

What is the result of the expression: (8 - 3) × 2 + 1?

Back

The result is 11, as you first calculate inside the parentheses, then multiply, and finally add.
