Question

Is 2,000 a good estimate for the difference between 4,315 and 156? If it is, explain why it is a good estimate. If it is not, explain why it is a bad estimate.

Answer 1

Answer:

2000 is not a good estimate for the difference of 4315 and 156.

Explanation:

For a number to be a good estimate between the sum or the difference between two numbers, those numbers must be close to the actual result.

Following this reasoning, we can say that 2000 is not a good estimate for the difference between 4315 and 156, since this difference results in 4159, which is a number very far from 2000.
