.. class:: infomark

**What it does**

This program implements arithmetic operations on tabular files data. The program takes three inputs:

- The first input is a TABULAR format file containing numbers only.
- The second input is a TABULAR format file containing numbers only.
- The third input is an arithmetic operation: +, -, x, or / for addition, subtraction, multiplication, or division, respectively. 
- The output file is a TABULAR format file containing the result of implementing the arithmetic operation on both input files.


Notes: 

- The two files must have the same number of columns and the same number of rows.
- The output file has the same number of columns and the same number of rows as each of the two input files.
- In case of division, none of the values in the second input file could be 0, otherwise the program will stop and report an error.

**Example**

Let us have the first input file as follows::

	5	4	0
	10	11	12
	1	3	1
	1	2	1
	2	0	4
	
And the second input file as follows::

	5	4	4
	2	5	8
	1	2	1
	3	2	5
	2	4	4

Running the program and choosing "Addition" as an arithmetic operation will give the following output::

	10	8	4
	12	16	20
	2	5	2
	4	4	6
	4	4	8
