NAME

multi.pl - multiplication table practice

SYNOPSIS

DESCRIPTION

This program lets (primary school) children practice their times tables.

USAGE

Make the script executable and put it in a directory that is in your path.

Start it by typing its name on the command prompt:

  multi.pl

It will repeatedly generate random integers between 1 and 12 inclusively and ask you to type in their product. If you give a wrong answer, you'll have to try again and succeed to continue.

Giving an empty responce by pressing the enter key alone will terminate the program and print out a summary of success.

You can influence the numbers generated in two ways:

-d|--difficult: The command line switch limits generated numbers to ones listed in an internal array: 4, 6, 7, 8, 9, 12.
integer argument: An integer argument sets the first item of the multiplication; you'll be practicing one particular multiplication table.

The above two methods can be combined to test, e.g, only ``difficult'' numbers in the 5 times table:

  multi.pl -d 5
