Answer:

7+2-5=f

Step-by-step explanation:

Draw a number line.

Imagine the ground as zero. If Kyle is 7 floors up, then he would be at positive 7.

If he goes up two more floors, he is adding, since he is getting farther away from "zero" or the ground floor.

If he goes down 5 floors, then he would be subtracting 5, since he is going down closer to ground floor.

Hope this helps! (Brainliest please!)
