Is there a possibility to do this riddle?

[miKers13]

Hi, Im obviously not very good at programming, but Id like to do this if possible: Is there a simple way how to assign All primitives, to (All) a set of numbers with a manually stated limit (or a limit set by computational capacities (limited via error, etc.), and further (manually) assign numbers (integers, decimal points and/or fractions) to All basic alphabetical letters, calculating, and writting All these assigned mathematical results to a manually limited memory and continuing further mathematical (also numerals assigned to letters) computations, based on the previous results (from memory) so far (looping).
Thanks so much
