How can estimating help you add two digit of number?

It is easier to simply add two one-digit numbers than to mess about with estimation!

How do you estimate 467.6 by 8?

To estimate 467.6 multiplied by 8, you can round each number to make the calculation easier. Rounding 467.6 to 470 and 8 to 10, you can multiply these rounded numbers (470 x 10) to get an estimated product of 4700. This estimation provides a quick approximation of the actual product without the need for precise calculations.


How many 4 digit number combinations are possible by using the same 6 numbers?

6 * 5 * 4 * 3 I'm sure you can calculate the answer from here. (that assumes you can't use an already used number again, if reuse is allowed the calculation is even easier)


Why might you estimate 26 plus 78 as 25 plus 75?

Estimating 26 plus 78 as 25 plus 75 is a form of rounding that simplifies the calculation while maintaining the overall magnitude of the numbers involved. By rounding down to 25 and 75, you are working with numbers that are easier to mentally add together quickly. This estimation technique is particularly useful when you need a rough answer or when exact precision is not necessary.


How do you estimate to check that your answer is reasonable?

To estimate an answer the numbers are rounded and the calculation done. It is often suggested to round to 1 sig fig as this will give a general indication of how big the answer should be. eg 1234 ÷ 31 → 1000 ÷ 30 ≈ 33.33 so an answer in the region of about 30 to 40 is expected. A slight variation from this can make the calculation easier, eg rounding the 1234 above to 2 sig fig gives 1200 ÷ 30 which is easier as 1200 is a multiple of 30 (and actually much closer to the real answer) giving 1200 ÷ 30 = 40; the real answer is approx 39.81.


Can text entries can be used in calculation using Excel?

Not in the sense that you can type the word of a number and/or operation to do a calculation, like having: =Five multiplied by seven =Ten + four =8 minus 2 However some text functions can be used to generate numbers, like finding the length of a piece of text and using that number in a calculation. You can also give cells actual names and then use those names in calculations, which can be easier than remembering cell addresses. So you could have a cell named Total and then do a calculation like this, using the word Total instead of the actual cell reference: =Total * 10%


What does the word front-end estimation mean?

Front-end estimation means that you estimate from the front of the number. say you're too lazy to work out 183 + 294. 183 becomes 180 and 294 becomes 290. now the problem is 180 + 290. see? much easier!


Why are commas used in large numbers?

They're simply used for clarity - to make the number easier to read.
