Ekspresi (matematika)

Penggunaan ekspresi dapat berupa yang sederhana:

${\displaystyle 0+0}$ 

${\displaystyle 8x-5}$    (polinomial linear)

${\displaystyle 7{{x}^{2}}+4x-10}$    (polinomial kuadrat)

${\displaystyle {\frac {x-1}{{{x}^{2}}+12}}}$    (ekspresi rasional)

sampai yang rumit:

${\displaystyle f(a)+\sum _{k=1}^{n}\left.{\frac {1}{k!}}{\frac {d^{k}}{dt^{k}}}\right|_{t=0}f(u(t))+\int _{0}^{1}{\frac {(1-t)^{n}}{n!}}{\frac {d^{n+1}}{dt^{n+1}}}f(u(t))\,dt.}$
