and the second one with

Arithmetic::PaperAndPencil is a module which allows simulating the paper and pencil techniques for basic arithmetic operations on integers: addition, subtraction, multiplication and division, but also square root extraction and conversion from a radix to another.
Actually, this module is the porting of a similarly-named Raku module.
When rendering an operation as HTML, the module displays spoken French sentences. If you know the equivalent sentences in another language, you can contact me to add the other language to the distribution, or you can even send me a patch. Thank you in advance.
To install this module, first check that the Perl version in use is 5.38 or higher. If necessary, install a recent version with perlbrew or similar.
Then download the repository from Github or from CPAN and run the following commands:
perl Makefile.PL
make
make test
make install
The first non-core prerequisite is
Test::Exception,
which is needed only if you run the extended tests in directory xt.
The other non-core prerequisites are
Test::CheckManifest,
Test::Pod::Coverage,
Pod::Coverage
and Test::Pod
which are used only if you run the RELEASE_TESTING tests.
After installing, you can find documentation for this module with the perldoc command.
perldoc Arithmetic::PaperAndPencil
You can also look for information at:
-
RT, CPAN's request tracker (report bugs here)
You can find some additional documentation about the mathematical topics in the repository for the Raku module:
You can find also some documentation about the Corinna implementation in the present repository:

This module is dedicated to my primary school teachers, who taught me the basics of arithmetics, and even some advanced features, and to my secondary school math teachers, who taught me other advanced math concepts and features.
