4 + (- 8)
Chips are used for doing integer arithmetic like this.
We have positive number 4
Negative number -8
Problem is their sum ?
We represent a chip by ()
Positive chip - (+)
Negative chip - (-)
4 + (-8)
(+) (+) (-) (-) = 0
(+) (+) (-) (-) = 0
(-) (-)
(-) (-)
Note (+) + (-) = 0
We now have a net 4(-) chips and our answer is -4
