7-3(-1)

7 + 3 = 11

oops, 10.

Sure, I can help you with that. When solving equations with parentheses, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). Let's break down the steps to solve the expression 7-3(4-5):

1. Start by simplifying within the parentheses first.

4-5 = -1

So now our expression becomes: 7-3(-1)

2. Next, apply the multiplication operation. Multiply the number outside the parentheses (in this case, 3) by the number inside the parentheses (-1).

3 * (-1) = -3

So now our expression becomes: 7 - (-3)

3. Finally, perform the subtraction operation.

7 - (-3) = 7 + 3 = 10

Therefore, the value of the expression 7-3(4-5) is 10.
