Answer 3

To solve the expression 12 + (-15) - (-13) - (-3) - 54, follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

Let's simplify the expression step by step:

First, simplify the negative signs: 12 + (-15) + 13 + 3 - 54

Next, perform addition and subtraction from left to right: -3 + 13 + 3 - 54 = 10 - 54 = -44

Therefore, 12 + (-15) - (-13) - (-3) - 54 equals -44.
