Answer 2

To solve the expression 750 - (60/10 * 50) + 640/80 - 70, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

Let's break down the expression step by step:

Step 1: Evaluate the expression inside the parentheses. 60/10 equals 6, so the expression becomes: 750 - (6 * 50) + 640/80 - 70

Step 2: Perform the multiplication and division from left to right. 6 * 50 equals 300, and 640/80 equals 8. The expression becomes: 750 - 300 + 8 - 70

Step 3: Perform the subtraction and addition from left to right. 750 - 300 equals 450, and 450 + 8 equals 458. The expression becomes: 458 - 70

Step 4: Perform the final subtraction. 458 - 70 equals 388.

Therefore, the answer to the expression 750 - (60/10 * 50) + 640/80 - 70 is 388.
