Negative Integers and Exponents
Marcus and Jeremy both evaluated the expression -52 + 3. Marcus
said the answer was -22. Jeremy said the answer was 28. Who is
correct? Explain the error in the other student's work.

Answer 1

Marcus is correct with the answer -49. When adding a positive and a negative integer, we subtract the two numbers and assign the sign of the larger number.

Step-by-step explanation:

To evaluate the expression -52 + 3, we need to add the two numbers. When adding a positive number and a negative number, we subtract the absolute value of the smaller number from the absolute value of the larger number and assign the sign of the larger number. In this case, -52 is larger than 3, so we subtract 3 from 52 and assign the negative sign, giving us -49. Therefore, Marcus is correct and the answer is -49, not -22 or 28.
