Question

an elevator is on the 10th floor. the elevator goes up 3 floors, then down 5 floors, then down another 2 floors before it stops. move values to the lines to create an expression that represents the floor on which the elevator stops. 10+ ____+__+____ -5 -3 -2 2 3 5

Explanation:

Step1: Analyze upward/downward movement

Going up 3 floors is represented by \( +3 \). Going down 5 floors is \( -5 \), and down 2 floors is \( -2 \).

Step2: Construct the expression

Start with initial floor 10. Add the movements: \( 10 + 3 + (-5) + (-2) \). So the blanks are filled with 3, -5, -2.

Answer:

The expression is \( 10 + \boldsymbol{3} + \boldsymbol{-5} + \boldsymbol{-2} \) (the values in the blanks are 3, -5, -2 respectively).
