Question

Yellow chip = +1 Red chip = -1Find the sum of 4 + -5 using the counter chips.4=-5=4 + -5 =

Answer 1

Notice that 5 is greater than 4.

To find 4-5, remember that when a greater number is subtracted from another, the result is a negative number. Then, the result is the same as the result of 5 minus 4 but with a negative sign.

Since 5-4 is equal to 1, then:

`4-5=-1`

Therefore, the answer is: -1.
