Question

Problem that would represent

an elevator starts at street
level (main lobby) goes up 6
floors and then back down 8
floors to the parking garage.

1 + 7 - 8 = 0
0 + 8 + (-2) = 6
1 + 6 + (-8) = -1
0 + 6 + (-8) = -2

Answer 1

1+6+(-8) = -1 is going to be your answer. aka C

Answer 2

`\\ \sf \longmapsto 1+6+(-8)`

• Downward motion noted as negative and upward is positive.
• Lobby will be 1

`\\ \sf \longmapsto 1+6+(-8)`

`\\ \sf \longmapsto 1+6-8`

`\\ \sf \longmapsto 7-8`

`\\ \sf \longmapsto -1`

option c is correct
