**Warning: There is a bad bug in the way the calculator parses some input, especially involving multiple digit numbers. This will be addressed soon.**

This calculator uses the Adem relations to express elements of the mod 2 Steenrod algebra in terms of the Serre-Cartan basis.

To evaluate (for example) *Sq ^{4}Sq^{20}+Sq^{8}Sq^{8}Sq^{8}*, use input format: 4 20 + 8 8 8

Currently this is the only input format supported, i.e. input must be a single Steenrod square, a product of squares, or a sum of products of squares - no parenthesization allowed!

Output is in the same format.
