Step 2:
Now, you have 63 + 40.
Step 3:
Finally, add the two numbers together: 63 + 40 = 103.
The correct answer is 103.
To evaluate this expression, you can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to PEMDAS, you need to perform any calculations inside parentheses first.
In this case, you have parentheses around the expression (12 + 28). To evaluate that part, simply add the numbers inside the parentheses: 12 + 28 = 40.
Finally, add the result of the parentheses to the number 63: 63 + 40 = 103.
So, the correct answer is 103.
