Write down any 3 digit number. It can be any number as long as the first and last digit differ by more than one. Now reverse the digits and take the smaller number away fron the larger one.

With your answer, now reverse these digits and add these two numbers together.

Please display your answer and compare it to other answers!

Wouldn't it be so simple to keep your negative comments as well as the derogatory language to yourself? It’s very easy to ignore a question rather than respond (with an incorrect answer). If someone is getting help with their homework so what? Sometimes people need help. If we harnessed the energy we waste writing negative comments or ignoring someone in need and then used it positively, this world would be a better place.

I am trying to pronounce the word Sadalsudd, a star in the constellation Aquarius as well as many other stars that have arabic origins. This star is shown to be pronounced as: Sa'd as-Su'ud

How do I know if the vowels are short or long? Any tips on pronouncing these stars in english? Here is a list of them http://www.icoproject.org/star.html

I know there are websites that pronounce the common stars but the obscure ones I can not find any help from the web. Any thoughts or help are welcomed.
