Rounding isn't necessary. The distributive property tells you that 13 x 9 = 90 + 27 = 117 If you have to, you could estimate that 10 x 10 = 100
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.

Rounding can help determine if an answer is reasonable by simplifying the numbers involved to make mental calculations easier. For instance, if you round numbers to the nearest ten or hundred, you can quickly estimate what the result should be. After performing the exact calculation, you can compare the result to your rounded estimate; if the answer is significantly different, it may indicate an error in the calculation. This method serves as a quick check to validate the plausibility of the solution.
Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.
331+193=524
You don't need to: the answer is 2560.
50.0000.000
40 x 30 = 1200
An estimate of 348 would typically be rounded to the nearest ten, hundred, or thousand depending on the level of precision needed. Rounding to the nearest ten would give an estimate of 350, rounding to the nearest hundred would give an estimate of 300, and rounding to the nearest thousand would give an estimate of 0.5. The choice of which rounding method to use would depend on the context in which the estimate is being used.
Not in this case.

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.
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."
When I shop I use rounding all the time and estimate the cost of things. That way I know if I have enough money to buy what I have in my cart. This works well and I am usually within a dollar or two of how much I am spending. Try it.
Use rounding and estimation to predict the approximate quotient of 285 ÷ 11.
