Question

A construction crew is digging a hole. On the first day, they dug a hole 3 feet deep. On the second day, they dug 2 more feet. On the third day, they dug 4 more feet. Write a sum of negative numbers to represent this situation. Find the total sum and explain how it is related to the question.

Answer 1

First off if you're adding the answer is 9 but if you are subtracting the answer is 1 because 4-3 is 1 and 1-2 is 1 so the answer is 1 but if you're multiplying the answer is 24 so 4 times 3 equals 12 and 12 times 1 equals 12 and 12 times 2 equals 24 .if you're dividing don't because you'll get the wrong answer

Answer 2

⇒Height  till which earth is dug on first day=3 feet deep

If represented in terms of Integer , it will be = -3

⇒Height till which earth is dug on Second day=2 feet deep

If represented in terms of Integer , it will be = -2

⇒Height till which earth is dug on Third day= 4 feet deep

If represented in terms of Integer , it will be = -4

Sum of Three Negative Integers

        = (-3) +(-2)+(-4)

        = -9----Addition of three Negative Integers yield negative result.

→ -9= Total Length of Earth Dug in the ground by Construction Crew in three days.
