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 helps remember the order of operations.

Front

Evaluate: 3 + 4 x 6 - 4

Back

First, perform multiplication: 4 x 6 = 24. Then, 3 + 24 - 4 = 23.

Front

What step comes first in the expression: 5 - 3 + 2?

Back

The first step is subtraction: 5 - 3 = 2, then add 2 to get 4.

Front

Evaluate: (4 - 2) x 9 + 7

Back

First, solve inside the parentheses: 4 - 2 = 2. Then, multiply: 2 x 9 = 18. Finally, add: 18 + 7 = 25.

Front

What is the first operation to perform in -2 * (3 + 8 ÷ 4)²?

Back

The first operation is division: 8 ÷ 4 = 2.

Front

What is the result of 15 - 3 + 2?

Back

First, perform subtraction: 15 - 3 = 12, then add 2 to get 14.

Front

What is the error in the calculation: 5 - 3 + 2 = 5 - 5 = 0?

Back

The error is that addition was done first instead of subtraction. The correct order is to subtract first.

Front

Evaluate: 8 ÷ 2 + 3 x 4

Back

First, perform division: 8 ÷ 2 = 4. Then, multiplication: 3 x 4 = 12. Finally, add: 4 + 12 = 16.

Front

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

Back

First, solve inside the parentheses: 3 + 1 = 4. Then, multiply: 2 x 4 = 8. Finally, add: 6 + 8 = 14.
