When the product of 1/3 and 1/2 is subtracted from the sum of 1/3 and 1/2 what is the difference. ANSWERS ASAP

"Difference between" means to subtract the first minus the second "Sum of" means to add the first plus the second "Product of" means to multiply the first times the second. what is [the difference between (the sum of 1/2 and 1/3) and (the product of 1/2 and 1/3)]? Then we do (the sum of 1/2 and 1/3) = 1/2 + 1/3 = 3/6 + 2/6 = 5/6.

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
