To estimate, you can round 627 up to 630 and round 253 down to 250.

650-250=380. 380 is your estimate.

The actual answer is 374.

If you round 627 to 630 and 253 to 250 then subtract it to get the difference of 380 then compare it to the actual answer of 374 this means that 380 is a good estiment
