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 operation inside the parentheses first, which is 3 + 5 = 8.

Front

In the expression 8 ÷ 2 × 4, which operation do you perform first?

Back

You perform division and multiplication from left to right, so 8 ÷ 2 = 4, then 4 × 4 = 16.

Front

What is the result of the expression: 6 + 2 × 3?

Back

According to the order of operations, you multiply first: 2 × 3 = 6, then add: 6 + 6 = 12.

Front

What is the purpose of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first in an expression.

Front

Evaluate the expression: 10 - 4 ÷ 2 + 3.

Back

First, divide: 4 ÷ 2 = 2. Then, perform subtraction and addition from left to right: 10 - 2 + 3 = 11.

Front

What is the result of the expression: 5 × (2 + 3)?

Back

You calculate inside the parentheses first: 2 + 3 = 5, then multiply: 5 × 5 = 25.

Front

In the expression 12 - (3 + 1) × 2, what do you calculate first?

Back

You calculate inside the parentheses first: 3 + 1 = 4, then multiply: 4 × 2 = 8, and finally subtract: 12 - 8 = 4.

Front

What is the result of the expression: 15 ÷ 3 + 4 × 2?

Back

First, divide: 15 ÷ 3 = 5. Then, multiply: 4 × 2 = 8. Finally, add: 5 + 8 = 13.
