Answer 2

Task Description

You have provided two mathematical expressions: - Expression A: (A) - (80 + 60) * 7 - Expression B: (B) - (65 - 40) * 4

You would like a detailed explanation of how to solve these expressions. Let's break them down step by step.

Expression A: (A) - (80 + 60) * 7

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Start by evaluating the expression inside the parentheses: 80 + 60 = 140. 2. Next, multiply the result by 7: 140 * 7 = 980. 3. Finally, subtract the result from the value of (A): (A) - 980.

Expression B: (B) - (65 - 40) * 4

Again, we will follow the order of operations to solve this expression.

1. Evaluate the expression inside the parentheses: 65 - 40 = 25. 2. Multiply the result by 4: 25 * 4 = 100. 3. Finally, subtract the result from the value of (B): (B) - 100.

Please note that the values of (A) and (B) are not provided in your question. To obtain the final result, you need to substitute the values of (A) and (B) into the expressions and perform the calculations.

I hope this explanation helps! Let me know if you have any further questions.
