Front

What should you solve first in the expression: 3 x 48 / (15 - 3)?

Back

15 - 3 (because of the parentheses).

Front

In the expression 2 + (9² - 4), what operation is performed first?

Back

The exponentiation (9²).

Front

What is the second step in solving (4-2) x 9 + 7?

Back

Multiplication (after subtraction).

Front

What is the result of the expression 15 + 7 × 2 – 11 + 35?

Back

53.

Front

How do you simplify the expression [(10-6) + (18-6)²]?

Back

First, calculate (10-6) = 4 and (18-6)² = 144, then add them: 4 + 144 = 148.

Front

What is the value of 9²?

Back

81.

Front

What is the result of 8 + 2 × 5?

Back

18 (because multiplication is done before addition).

Front

What is the first step in solving 12 - (3 + 1) × 2?

Back

Calculate the expression in parentheses: (3 + 1) = 4.
