You use rounding TO estimate. For instance, estimating is 2.8 + 3.9 is about 7. Rounding is 2.8 is about 3 and 3.9 is about 4. When you estimate, you're rounding MULTIPLE numbers which you will then add, multiply, etc. to get an ESTIMATE! when you're rounding, you need to be given a certain number and you make it less specific. for example, the population of whoville is 693044. if I'm rounding to the nearest thousand, then the answer is 693000. numbers 5 and up are rounded up. numbers 4 and below are rounded down. when you're estimating, you're basically making an educated guess without knowing the real number. for example, you're looking at a bag of jellybeans and you guess there's 750 in there. it seems like a reasonable number so you estimate that.
