Question

Explain how you can use chips to determine the sum

Answer 1

Explanation:

To solve this problem using chips; Check out the analogy below:

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
