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"
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. (Nikola Tesla)
