Hello...
Today at the DRCSS we did Tutorial 2.2- Multiplying Matrices..
When multiplying a Matrice, multiply the first number in the row by the first number in the column.. then multiply the second number in the row by the second number in the column.. and so on then add the products.

** Two matrices, A & B, can be multiplied to form A X B only if:

• The Number of columns in A = The number if rows in B

If this is so. then the product matrix AB will have the same number of rows as A & the same number of columns as B.
Example: Amxn X Bnxp = ABmxp
--->> m,m are dimentions of product matrix.
--->> n,n must be equal.
*When you multiply matrices, AxB doesn't necessarily equal BxA

For today's assignment we had done questions 1,2,3,4, and your choice of either 5 or 6, on Page 64.
