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 for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which helps remember the order of operations.

Front

What is the first step in the expression 5 + 2 × 3?

Back

The first step is to perform the multiplication: 2 × 3 = 6.

Front

Evaluate the expression: 8 - 3 + 2.

Back

The correct evaluation is 7. (First subtract: 8 - 3 = 5, then add: 5 + 2 = 7.)

Front

What does 4^2 mean?

Back

4^2 means 4 multiplied by itself: 4 × 4 = 16.

Front

In the expression 6 + (2 × 3), which operation is performed first?

Back

The multiplication inside the parentheses is performed first: 2 × 3 = 6.

Front

Evaluate the expression: (3 + 5) × 2.

Back

The correct evaluation is 16. (First add: 3 + 5 = 8, then multiply: 8 × 2 = 16.)

Front

What is the result of 10 - 2 + 4 × 3?

Back

The correct result is 20. (First multiply: 4 × 3 = 12, then subtract and add: 10 - 2 + 12 = 20.)

Front

What is the value of 2 × (3 + 4) - 5?

Back

The value is 9. (First add: 3 + 4 = 7, then multiply: 2 × 7 = 14, and finally subtract: 14 - 5 = 9.)
