Det er at lægge to tal sammen inden for <a href="/wiki/Matematik" title="Matematik">matematikken</a>. I <a href="/wiki/Aritmetik" title="Aritmetik">aritmetikken</a>, er addition en af de grundlæggende operationer. Additionen er en <a href="/wiki/Bin%C3%A6r_operation" class="mw-redirect" title="Binær operation">binær operation</a>, da der skal være to tal at lægge sammen. Den betegnes ved symbolet +. Hvis man for eksempel har 4 æbler og 3 æbler, så er summen det antal æbler man vil få ved at blande de to samlinger, og tælle dem igen. Summen udtrykkes 4 + 3, og resultatet er 7. </p><p>Operatoren hedder plus, mens selve operationen hedder <i>at addere</i> eller <i>at lægge sammen</i>. Resultatet af operationen hedder <i>summen</i>. </p><p>Der findes endvidere en sumoperator angivet ved et stort <a href="/wiki/Gr%C3%A6kenland" title="Grækenland">græsk</a> <a href="/wiki/Sigma_(bogstav)" title="Sigma (bogstav)">sigma</a>, som primært bruges som ren notation, eller i forbindelse med meget lange summer (evt. uendelige). Operatoren har et såkaldt indeks som angiver hvor summen starter, og slutter. Indekset angives i bunden sammen med summens start, og summens slut angives i toppen, som vist nedenfor: </p><p><span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y"
