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

The answer depends on your familiarity with number bonds.

You need to understand that a mixed number such as 5 1/3 really means 5 plus 1/3. You can do your calculations accordingly. To add and subtract, you can add and subtract the whole part and the fractional part separately. To multiply or divide, you can convert the numbers to improper fractions first - though in some cases it is easier to use the distributive property.

Less digits to work with. As an example, to multiply 4000 x 30,000, you only need to multiply 4 x 3, then attach all the zeros (7 zeros in this case) at the end. WITH A LITTLE BIT OF PRACTICE, YOU CAN DO THIS CALCULATION IN YOUR HEAD. However, if there are more significant digits (roughly speaking, non-zero digits), most people would need pencil and paper, or a calculator, to do such a calculation.

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)

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%

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!

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

The numbers in the simplified form are smaller and so may be easier to comprehend. Also, working with the lowest terms means that the results of multiplications or divisions are smaller numbers and so less susceptible to errors - either calculation mistakes made by the user or rounding errors because computers can store and manipulate numbers to only a limited degree of accuracy.
