Large Number Math Checker
Here’s a cool tool for checking that large number multiplication or division. Its a MS Excel spreadsheet set up to do either multiplication or division. I don’t, of course, advocate the use of this tool instead of working the problem yourself, but its a good way to check your work.
This MS Excel spreadsheet should work fine with open source alternatives that can open and edit .xls files, including OpenOffice.org and Gnumeric.
Just click on the screenshot below to download the spreadsheet in .zip format, ready to decompress and use!
