Answer 1

1)36:3=12
2)12*2=24
3) 90-24=66

Answer 2

To solve the given expression: 90 - (36 ÷ 3) × 2, we need to follow the order of operations, also known as the PEMDAS rule.

PEMDAS stands for:

• Parentheses: Perform operations inside parentheses first.
• Exponents: Solve any exponentiations or powers.
• Multiplication and Division: Perform multiplication and division from left to right.
• Addition and Subtraction: Perform addition and subtraction from left to right.

Let's apply these rules step by step:

Step 1: Start with the parentheses. In the expression, we have (36 ÷ 3). Evaluating this division, we get 12.

Step 2: Perform multiplication. Now we have 90 - 12 × 2. Multiplying 12 by 2 gives us 24.

Step 3: Perform subtraction. Finally, we have 90 - 24. Subtracting 24 from 90 gives us the final result.

Step 4: Calculate the subtraction. 90 - 24 equals 66.

Therefore, the solution to the given expression 90 - (36 ÷ 3) × 2 is 66.
