1. The range is the numbers that the answer must fall between.

3.89 = about 4
42.71 = about 43
12.32 = about 12

The range must be 58 - 60

10. Front end estimation will answer the question for you

Front end estimation mostly produces a closer estimate of sums or differences than the answer produced by adding or subtracting rounded numbers.

How to estimate a sum by front end estimation:

Add the digits of the two highest place values
Insert zeros for the other place values

Example 1: 4496 + 3745 is estimated to be 8100 by front end estimation (i.e. 4400 + 3700).
Example 2: 4496 + 745 is estimated to be 5100 by front end estimation (i.e. 4400 + 700).
