Fractions²

Fractions²

 

Description

Our calculator does mixed fractions & decimal arithmetic with support for brackets. This covers most of the work you need to do with fractions but we also record the results to a "paper tape" which you can scroll to review and then email to yourself so you can see and record the sum of your labours.

For example you can enter

5 3/16 + (12.11 - 1/8)*2 =

to get the answer 29 63/400 which you can then show as

11663/400, or 29.1575

All this on a calculator tape that we remember between sessions so you don't have to remember how you arrived at the 29.1575 number the day after. Plus with sound feedback you can turn off or on means you get audible feedback when tapping our keyboard button images.

Since we support the power function we let you choose if

-3^2=-9 or 3^2=9.

Huge debate on this, Microsoft has one answer, but your college math professor has a different answer.

WolfRam Research's Alpha

http://www.wolframalpha.com/input/?i=-3%5E2

Says '-9', but Microsoft Excel would answer '9'.

But we let you choose if the answer should be -9 or 9, so you can make either party happy. Hint your professor/teacher is likely the one that should be happy, ask him his opinion.

How do I enter a Fraction?

To enter 3/4 tap

'3'

'½' the fractions key. then

'4'

This will show 3/4 in the tape

To enter 9 3/4, a mixed fraction, tap

'9'

'½' the fractions key and press

'½' again to signify you are entering a mixed fraction then

'3' and

'½' the fractions key to say it's a fraction, and finally

4

This will show 9_3/4 in the tape.

Email us at help@mobilewikiserver.com if you have questions.

We are also unique in the way we handle unlimited sized fractions, and factorials. For example you can calculate this factorial based fraction.

512!/513!

Which answers 1/513, and requires the manipulation of a 1, 170 and 1, 167 digit number.

Or calculate 2^151 "2 to the power of 151" to get 2854495385411919762116571938898990272765493248
