Matrix operations challenge

Question

Try to check logical of the matrixes and make a code to ask user for the first (Matrix 1) and show outputs for Matrix 2 and Matrix 3:

Matrix 1
42 18
35 72

Matrix 2
6,48 4,24
5,916 8,48

Matrix 3
6 4
6 8

To get Matrix 2, you must to apply an operation to each elements in Matrix 1 and in the same way, to get Matrix 3, you must to apply an operation to elements in Matrix 2.

Let's do it if you want but it's not a task, it's a challenge to improve your skills. It's a simple exerci

Answer 1

Well, here is mine :)
I just did it for 2x2 matrixes because I realized too late that matrixes can be any size jajajaja.

Edited: Now it works with NxN matrixes ^^

Answer 2

Here is mine.

It works propperly now. (changed int --> round).

First enter the number of rows, press enter.
Than enter the rows with spaces between the numbers:

example:

3
1 2 3
4 5 6
7 8 9
