Hi, I assume that the question you want answered is Qn 10, since the other two already have answers filled in?
Estimate means giving a rough answer, which is not the accurate answer, but close to it.
For example, in this question, the actual answer is
714+492-189 = 1017
But after you round each number to the nearest hundred as the question asked you to do , it becomes
700+500-200 = 1000 (estimated answer)
As you can see the estimated answer is quite close to the actual answer.
