Why is 16.7 a reasonable sum for 7.5 9.2?
7.5 + 9.2 = 16.7So 16.7 is reasonable.===========================You should not have to perform the addition in order to decide whether an estimatewas reasonable. That defeats the whole purpose of the estimating process.Ignore the decimal parts of your two numbers, and you have (7 + 9). You don't needa calculator to know immediately that THAT sum is 16. So 16 is a good estimate forwhat you'll have when you glue the decimal bits back onto the whole numbers, andwhen you reassemble everything and get a sum of 16.7 , that's so near your estimatethat you can be pretty sure that you added correctly.
