A fast method for estimating the total of two numbers involves rounding each number and adding the rounded results.

case a) We round to the nearest hundred

so

196 Round up equals 200

482 Round up equals 500

Calculate the estimated sum

200+500=700

case b) We round to the nearest ten

so

196 Round up equals 200

482 Round down equals 480

Calculate the estimated sum

200+480=680
