1) 26-54=-28
2)-15-28= -43

Answer 3

To calculate the expression, you need to follow the order of operations, which is typically remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). In this case, you should first perform the operation inside the parentheses, and then the subtraction:

-15 - (26 - 54)

Step 1: Solve the operation inside the parentheses: 26 - 54 = -28

Step 2: Perform the subtraction: -15 - (-28)

To subtract a negative number, you can think of it as adding the absolute value of that number. So, the expression becomes:

-15 + 28 = 13

Therefore, the result of the expression is 13.
