Mathematics also studies models, shapes, curves, cardinals, similarity, consistency, completeness, space ...
Among objects of mathematical study are heredity, continuity, jumps, infinity, infinitesimals, paradoxes...
Last but not the least, Mathematics studies stability, projections and values, values are often absolute but may also be extreme, local or global.
Trigonometry aside, Mathematics comprises fields like Game Theory, Braids Theory, Knot Theory and more
One is morally obligated not to do anything impossible
Some numbers are square, yet others are triangular
The next sentence is true but you must not believe it
