"Mathematics is made of 50 percent formulas, 50 percent proofs and 50 percent imagination” is a math joke—the percentages add up to 150 percent, not 100 percent. The joke was printed in *Pi in the Sky* (June 2001) by The Pacific Institute for the Mathematical Sciences (Alberta, Canada).

Authorship of the joke is unknown.

*Is this true: “Mathematics is made of 50 percent formulas, 50 percent proofs, and 50 percent imagination”?*

First exercise in mathematics: add correctly. 50% of A plus 50% of B plus 50% of C make 150%, not 100.

Then: that is way too formalistic. Formulas play a much smaller role in math, than most laypeople actually believe. Algebraic calculation is a basic skill needed for most of math, and some are better than others, but it is not a central capability that constitutes a mathematicians. Personally I always had the impression, that for example theoretical physicists were much better at formula calculations than me and my math colleagues.

Did they just miss the whole point? Or is that the whole point? Does this mean whatever answer we come up with is the right one? Yes, let’s go with that.

Mathematics is made of 50 percent formulas, 50 percent proofs, and 50 percent imagination. An engineer thinks that his equations are an approximation to reality. A physicist thinks reality is an approximation to his equations. A mathematician doesn’t care.
