You can do arithmetic with Mathematica
just as you would on an electronic calculator.
Arithmetic operations in Mathematica
are grouped according to the standard mathematical conventions. As usual, 2^3+4
, for example, means (2^3)+4
, and not 2^(3+4)
. You can always control grouping by explicitly using parentheses.
, you can perform calculations with a particular precision, usually higher than an ordinary calculator. When given precise numbers, Mathematica
does not convert them to an approximate representation, but gives a precise result.
