Shira had a checking account balance of $653.22 at the beginning of the month. She deposited two paychecks, one for $108.35 and the other for $175.23. She wrote three checks: one for $25.00, one
for $323.50, and one for $38.00. Her monthly service fee was $3.00. What is Shira's new account
balance?

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

is there any photos or whatever?
