Question

You decide to see if you can ride the elevator to street level (Floor 0) without pushing any buttons. The elevator takes you up four floors, down 6 floors, up 1 floor, down 8 floors, down 3 floors, up 1 floor, and then down 6 floors to street level. Write an equation to find your starting floor.

Answer 1

Well, you start from street level, then reverse up and down.
Street level = 0
down = +
up = -
Answer
= 0 + 6 - 1 + 3 + 8 - 1 + 6 - 4
= 17
You started to ride the lift on 17th floor

Answer 2

Awesome, thanks very much!

Answer 3

Can anyone help me by putting this into an algebraic expression?

Answer 4

Where x is the floor you start from,
x = 0 + 6 - 1 + 3 + 8 - 1 + 6 - 4
x = 17

Answer 5

oh wait

Answer 6

This is how the problem expressed in algebra equation:
x + 4 - 6 + 1 - 8 - 3 + 1 - 6 = 0

Try to solve that, answer should be the same.
