yay for blogs

This week i am doing my blog on MATRIX MULTIPLICATION!!! YAY!!!

Notes:
-To Multiply Matrices, you have to look at the dimensions of each matrix to see if it is even possible first.
a x b b x c
-The two inner numbers of the dimensions must match for you to be able to multiply.
-The resulting matrix will be the two outside numbers.
a x c

Example: Multiply matrix {2 4} by matrix {4}
{3 1} {2}

2 x 2 2x 1

the inside numbers match and the answer will be a 2 x 1 matrix

Now you do 2 x4 + 4 x2 = 16
Next is 3x 4 + 1 x 2= 14

The end matrix is {16}
{14}



YaY we did it!! goodnight everyone
