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 problem.

Answer 1

Answer: It would be dug 9 feet deep hole in the ground.

Step-by-step explanation:

Since we have given that

On the first day , they dug a hole of length = 3 feet

On the second day, they dug a hole of length = 2 feet

On the third day , they dug a hole of length = 4 feet

Since all the above integers are negative integers as they are length beneath the ground.

So, Sum of negative numbers would be

$-3-2-4$

And the total sum would be

$-3-2-4=-9\ feet$

Hence, it would be dug 9 feet deep hole in the ground.

Answer 2

(-3)+(-2)+(-4)= -9. The hole is 9 feet deep. It's related to the problem because it's the total depth of the hole.
