What is \(4 + (-5)\)?

That's the same as starting from the lobby, taking the elevator UP four floors, then taking another elevator DOWN 5 floors. Where do you end up ?
(positive 4) + (negative 5) =*** -1***

Your answer is going to be -1. 4+(-5) changes to 4-5, which equals -1.

The expression 4 + ( − 5 ) simplifies to 4 − 5 = − 1 . Therefore, the final answer is − 1 . This represents moving left on a number line from 4 to − 1 .
