What are your estimates?
343+ -42 - 402
My estimate is -102
Actual answer = -101
I'll be glad to check your answers.
Estimate each of the following and then use a calculator to find the actual answer:
a: 343+ -42 - 402
b: -1992 + 3005 - 497
c: 992 - -10,003 - 101
d: -301 - -1303 + 4993

Don't worry too much if your estimate is far different from the actual answer. We learn by making mistakes. :-)
