FactorX5 was a tiny software for the CASIO PRIZM to compute the prime factors of a given number. I have lost the exact date of the screenshot, but it was in 2012.

Mark3 was a tiny software for the CASIO PRIZM for computing the score of a test. We used it a lot to see what is our score and I remember how my friends would stand in line to get their scores with it. I have lost the exact date of the screenshot, but it was in 2012.

Roman was a tiny software for the CASIO PRIZM to compute the Roman Numeral of a given number. It was the most satisfying little software I wrote back in those days. I have lost the exact date of the screenshot, but it was in 2012.

Torr was a tiny software for the CASIO PRIZM to compute the Torr pressure unit to Pascal and vice versa. I have lost the exact date of the screenshot, but it was in 2012.
