No.
Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.
2 subtracted by 3 = -1

The first matrix has 3 rows and 2 columns, the second matrix has 2 rows and 3 columns. Two matrices can only be multiplied together if the number of columns in the first matrix is equal to the number of rows in the second matrix. In the example shown there are 3 rows in the first matrix and 3 columns in the second matrix. And also 2 columns in the first and 2 rows in the second. Multiplication of the two matrices is therefore possible.
(10 + 2 + 3 + 2 - 2)/(20 + 4 + 6) = 15/30
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
The number that when multiplied by 3, then 4 is subtracted and 2 added and the answer is 16 would be 6 .
2 subtracted by 3 = -1
1 subtracted by 3 and one half = -2
1 over 3 subtracted from 2 over 3 would yield 1 over 3.

2x + 7 - 3 = 0 ie 2x + 4 = 0 2x = -4 x = -2

The order of a matrix is another way of saying the dimensions of of a matrix. For a two dimensional matrix, the order could be 2 by 2, or 3 by 3, or 32 by 64.
