# How do you compute the dot product for <6, 1>*<-2, 3>?

Oct 4, 2016

(6)(-2) + (1)(3) = -9

#### Explanation:

For any two vectors, $\overline{a}$ and $\overline{b}$, of the forms

<${a}_{1} , {a}_{2} , \ldots {a}_{n}$>

and

<${b}_{1} , {b}_{2} , \ldots {b}_{n}$>

the dot is:

bara•barb = (a_1)(b_1) + (a_2)(b_2) + ... (a_n)(b_n)
