precision
To check math answers, you can use reverse operations to see if you arrive back at the original problem. For example, if you solved an equation, substitute your answer back into the equation to verify if both sides are equal. Additionally, you can use estimation to see if your answer is reasonable or employ a calculator for verification. Lastly, checking your work step-by-step can help identify any errors in your calculations.
To double-check division problems, you can multiply the quotient by the divisor to see if it equals the original dividend. For example, if you divided 24 by 4 and found the quotient to be 6, multiply 6 by 4 to verify that it equals 24. Additionally, you can estimate the division by rounding the numbers to see if your answer seems reasonable. Lastly, check your calculations or use a calculator for verification.
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.

Rounding in Visual Basic is the method of rounding an integer up, or flooring an integer, which is rounding down. To round up, you use the System.Math.Round function. To round down, or floor, you use the System.Math.Floor function.
My math teacher started rounding in the third grade and it has followed me since. Another use might be, "They were just rounding the bend when he came into sight."
Use rounding and estimation to predict the approximate quotient of 285 ÷ 11.

if you had an adding sum we would use it and if you were estimating
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.
yeah you can especially if your trying to be reasonable..loll
