based on an earlier version of the Wolfram Language.
 Arithmetic Functions Mathematica immediately allows you to do arithmetic not only with individual numbers, but also with arbitrary lists or arrays—as well as symbolic and algebraic forms. Mathematica uses the latest platform-optimized algorithms to work with exact and approximate numbers up to billions of digits, as well as polynomials with millions of terms. Plus (+) — addition of numbers, lists, arrays or symbolic expressions Subtract (-) — subtraction Times (×) — multiplication, entered as a space, * or × (Esc * Esc) Divide (/) — division, also entered as ÷ (Esc div Esc) Power (^) — power, entered as a superscript using Ctrl+^ Sqrt — square root, entered as using Ctrl+@      Total — total of elements in a list Mean — mean of a list Accumulate — cumulative sums in a list Differences — successive differences in a list Ratios — successive ratios in a list TUTORIALS Arithmetic Some Mathematical Functions MORE ABOUT Numerical Functions Polynomial Manipulation Numerical Data and Arrays Sparse Arrays RELATED LINKS Demonstrations related to Arithmetic Functions (The Wolfram Demonstrations Project)
