Python includes conventional symbols for arithmetic operators (+, -, *, /), the floor-division operator //, and the modulo operator %. (With the modulo operator, a remainder can be negative, e.g., 4 % -3 == -2.) Python also offers the ** symbol for exponentiation, e.g. 5**3 == 125 and 9**0.5 == 3.0; it also offers the matrix‑multiplication operator @ .cite-ref-109[106] These operators work as in traditional mathematics; with the same precedence rules, the infix operators + and - can also be unary, to represent positive and negative numbers respectively.

Division between integers produces floating-point results. The behavior of division has changed significantly over time:cite-ref-pep0238-110-0[107]

• The current version of Python (i.e., since 3.0) changed the / operator to always represent floating-point division, e.g., 5/2 == 2.5.
