Question

Matrices help!

Answer 1

hmm have you done matrix addition yet?

Answer 2

nope :x

Answer 3

lie.

Answer 4

heheh

Answer 5

busted !

Answer 6

We did it just 2 days ago @Buddhayourlord&savoir xD

Answer 7

if i understood how to do it wouldnt be asking :/

Answer 8

Oh well this is a bit difficult than the one you asked before.

Answer 9

halp

Answer 10

so the matrix addition will be
\( \Large \left[
\begin{matrix}
a& b\\
c& d
\end{matrix}\right] +
\left[
\begin{matrix}
e& f\\
g& h
\end{matrix}\right]
= \left[
\begin{matrix}
a+e& b+f\\
c+g& d+h
\end{matrix}
\right]
\)

Answer 11

so what's an "additive inverse"?

well, that just means another number that when added to this, will give 0
so if I have
25
what's the additive inverse of 25?
well, 25 + n = 0
what's "n" well, n = -25

25 - 25 = 0

the additive inverse of 25 is -25

Answer 12

$$ \Large {
\left[
\begin{matrix}
5&0&-1\\
3&2&4\\
8&-6&7
\end{matrix}\right] +
\left[
\begin{matrix}
\square&\square&\square\\
\square&\square&\square\\
\square&\square&\square
\end{matrix}\right]
= \left[
\begin{matrix}
0&0&0\\
0&0&0\\
0&0&0
\end{matrix}
\right]
}
$$

Answer 13

\[\left[\begin{matrix}a & b \\ c & d\end{matrix}\right] + \left[\begin{matrix}-a & -b \\ -c & -d\end{matrix}\right]=0\]

Answer 14

that should be [0] the zero matrix

Answer 15

so make the exact same matrix and flip the signs....

Answer 16

Is every additive inverse problem like this?

Answer 17

what @zzr0ck3r said

Answer 18

additive inverse just means what do you need to add to a matrix to equal the additive identity which is the 0 matrix

Answer 19

thank you @zzr0ck3r and @jdoe0001
