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"
Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. (Bertrand Russell)
