# Vektorer

> Vektorer har både storlek och riktning och används för att beskriva förflyttningar och krafter.

Vektorer är storheter med både riktning och längd.

## Representation

En vektor kan skrivas som en riktad sträcka eller som koordinater.

## Operationer

Vektorer kan adderas, multipliceras med skalärer och kombineras med skalärprodukt.

## Sammanfattning

Vektorer är viktiga i geometri, fysik och linjär algebra.
