Front

What is the first step in solving the expression 90 - 5^2 × 3?

Back

The first step is to calculate the exponent: 5^2 = 25.

Front

How do you solve the expression (5 × 6) ÷ (10 - 5)?

Back

First, solve the parentheses: 10 - 5 = 5. Then, calculate: (5 × 6) ÷ 5 = 6.

Front

In the expression 25 x (3-1), which operation is performed first?

Back

Subtraction is performed first: (3 - 1) = 2.

Front

What is the result of the expression 7[12 − (6 − 2) ÷ 4]?

Back

First, solve inside the parentheses: (6 - 2) = 4. Then, 4 ÷ 4 = 1. Now, 12 - 1 = 11. Finally, 7 × 11 = 77.

Front

What is the value of the expression 20 + (7 – 2) × 2?

Back

First, solve inside the parentheses: (7 - 2) = 5. Then, calculate: 5 × 2 = 10. Finally, 20 + 10 = 30.

Front

What is the order of operations in PEMDAS?

Back

The order is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What is an example of an expression that requires the use of PEMDAS?

Back

An example is: 3 + 6 × (5 + 4) ÷ 3 - 7.

Front

How do you handle multiplication and division in PEMDAS?

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 PEMDAS?

Back

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