I don't understand my exercise

don't give me any code
just a hint
a translation to normal english
thanks

Do you know what a Matrix is (not the movie) but in mathematical terms?

What Pascal data structure does a matrix look like?

How do you add one matrix to another?

Your best bet is the next day in class, get your hand in the air and ask questions.  Get your instructor to explain the assignment.
If you ask the right questions he might even do one of the parts for you.

A matrix is a mathematical entity that is useful in solving a variety of problems.  Is has rows and columns of numbers

  2    2
  3    4

This is  a 2x2 matrix


Adding is done by elements

  a  b           e  f         a+e   b+f
  c  d    +     g  h   =   c+g   d+h


Subtracting is similar.
