In this matrix can you solve it using addition?


[A]
[ 2 1 ]
[ 2 3 ]

+

[C] [ 0 1 ]

Find: [A] + [C]

can you add those?

the answer is 43.

No one can be told what the Matrix is.....

Why, oh why, didn't I take the BLUE pill??

do you have a graphing calculator?

those things solve matrix problems.
thats why they are recommended in your syllabus.

No


To add matrixies they have to be dementionaly equivelent. for example a 3x3 matrix + another 3x3 matrix not a 2x2 and a 1x2 like you got there. Now you could multiply those two.

Somebody forget to do their homework again?

No. You can multiply matrices of different dimension, though. [[2 1][2 3]] * [0 1] = [1 3]

That's different from the short bus you rode to school.

Thanks.

I really wish I had taken some advanced matrix algebra classes as an undergrad. They would have made grad school much easier.


Try doing MANOVA analyses by hand, using matrix algebra - then you really appreciate stats packages like SAS and SPSS

What's all this talk about demented matrices???

Ah, matrices!

Thanks! That is what I thought but I wanted to make sure.

Math, IMO, is the best subject and more the better! and the same for Science!
