'''Taran''' [[Xisaab]] ahaan {{en|Product}} waa natiijada [[Iskudhufasho]] laba walxoox. Kala hormarinta ay imaanayso [[Tiro maangal ah|tirooyin maangal ah]] ama [[Tiro kakan|kakan]] ee howlgalka iskudhufashada kumana lahan wax saamayn ah qiimaha taranta. Tani waa gaar ahaansho loola jeedo howsha iskudhufas bhada ee Kala-hormarinta.

Si kooban Taran waa wixi ka soo baxa laba tiro oo la isku dhufto sida 2*2= 4 markaa afar waa Taranta 2*2.

== Taran laba tiro ==

=== Taran laba tiro tirsiimo ===
[[file:Three by Four.svg|thumb|3 lagu dhuftay 4 waxay la midtahay 12]]

Dhig tirooyin kubbado ah qaab ah laydi tirooyinka sadaradiisa <math>r</math> tiri qotimadiisa <math>s</math> wuxuu ku siinayaa :
:<math> r \cdot s = \sum_{i=1}^s r = \sum_{j=1}^r s </math>
kubbad.

=== Taran laba tiro tirsiimo ===
:<math>\begin{array}{|c|c  c|}\hline
\cdot & - & + \\ \hline
  -   & + & - \\

\end{array}
</math>

Haddii si kale loo dhigo:
* Tranta laba tiro tabaneyaal ah waxay la midtahay tiro togan.
* Taranta tiro taban iyo tiro togan waxay la midtahay tiro taban.
* Taranta tiro togan iyo tiro taban waxay la midtahay tiro taban.
* Taranta laba tiro oo togan waxay la midtahay tiro togan.

=== Taranta laba jajab ===
Taranta laba jajab waa jajab sareeyihiisu la midyahay taranta laba jajab fudud hooseeyihiisu wuxuu la midyahay taranta hooseeyahay laba jajab, sida lagu muujiyay habkaan soo socda:
:<math> \frac{z}{n} \cdot \frac{z'}{n'} = \frac{z\cdot z'}{n\cdot n'}</math>

=== Taranta laba taxane ===
Si ay u noqoto laba taxaneyaal

:<math> A = (a_{i,j})_{i=1\ldots s;j=1\ldots r} \in \R^{s\times r}</math> و <math> B = (b_{j,k})_{j=1\ldots r;k=1\ldots t}\in \R^{r\times t}</math>

Tarantoodu waa:

:<math> B \cdot A = \left( \sum_{j=1}^r a_{i,j} \cdot b_{j,k} \right)_{i=1\ldots s;k=1\ldots t} \;\in\R^{s\times t} </math>
