Sponsor: Magic Number

Here is a smart calculator you will enjoy. Unlike a dumb calculator, it lets you see math as math. Typing is completely “what you think is what you type”. Everything is easier. Nothing gets in your way.


Magic Number is ideal for ‘back of the envelope’ calculations. Or cases when a spreadsheet feels like a truck and a traditional calculator feels like a horse.

Want to know the percentage increase going from 72 to 90?
Just type “72 + ?% = 90” and let Magic Number do the algebra.

Want to make sense of a list of prices?
Then the List feature is for you. You can see the statistics, compare prices,
and calculate their tax effortlessly.

I can go on. Magic Number is deep. But its virtue lies in its thoughtfulness.
