The new Office OneNote 2007 has a built-in Calculator, really nice stuff!

To try it out, just write a mathematic formula in a page and end with an equals sign followed by enter or space, for example:3+2=This will result in a row like this:3+2=5

It is quite powerful, it can handle operations like:

  • +, -, /, *
  • parenthesis so you can do formulas like this (3+3)*3=18
  • ^, for example 10^3=1 000
  • sqrt(n) for square root
  • sin(n), asin(n), cos(n), acos(n), tan(n), atan(n)
  • mod for modulus

And I’m sure there are more…
