A calculator for math operations and conversions.

Type an expression like, say '2+2' and click '='.
  • plus (a+b): 2+3=
  • minus (a-b): 2-3=
  • multiplication (a*b): 2*3=
  • division (a/b): 2/3=
  • exponential (a^b): 2^3=
  • modulus (a%b): 2%3=

Binomial expressions only (two numbers, one operator).
Negative numbers are typed like this: "-3"
I admit that twice two makes four is an excellent thing, but if we are to give everything its due, twice two makes five is sometimes a very charming thing too. (F. M. Dostoyevsky)
