What is it called when you put two of the same variables together

In algebra, like terms are terms that have the same variables and powers.

In algebra, like terms are terms that have the same variables and powers.

I hope this helps!

Step-by-step explanation:

If you have 4y and 8y you have like terms because they are the same and you would get 12y

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
