7BOrder of Operations

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The common acronym to remember this is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is the first step in solving the expression 6^2 - 92 ÷ 4?

Back

The first step is to calculate the exponent: 6^2 = 36.

In the expression 70 ÷ 5 - 2^3, what operation should be performed after division?

Back

After division, the next operation to perform is exponentiation: 2^3 = 8.

What is the result of the expression 3^3 ÷ 9 + 2?

Back

The result is 5. First, calculate 3^3 = 27, then 27 ÷ 9 = 3, and finally 3 + 2 = 5.

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

Back

The result is 22. First, calculate the exponent: 2^2 = 4, then 6 × 3 = 18, and finally 18 + 4 = 22.

What is the significance of parentheses in the order of operations?

Back

Parentheses indicate that the operations within them should be performed first before any other operations.

Front

How do you handle multiplication and division in the order of operations?

Back

Multiplication and division are performed from left to right as they appear in the expression.

Front

How do you handle addition and subtraction in the order of operations?

Back

Addition and subtraction are also performed from left to right as they appear in the expression.
