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

To evaluate the expression \(-52 + 3\), we start with \(-52\) and then add \(3\) to it.

Here are the steps:

1. Start with \(-52\).
2. Add \(3\): \[ -52 + 3 = -49 \]

So the correct answer is \(-49\).

Marcus's error: Marcus said the answer was \(-22\). It seems he may have miscalculated by perhaps adding incorrectly or misinterpreting the negative value.

Jeremy's error: Jeremy said the answer was \(28\), which seems to be a misunderstanding as he likely disregarded the negative sign and incorrectly interpreted it as a positive calculation or confused with some other operation.

In conclusion, neither Marcus nor Jeremy got the correct answer, which should be \(-49\).
