Commemorative stamps that honor the contributions of Isaac Newton and Gottfried Leibniz, the co-fathers of Calculus, to mankind.
How many philaculus first day covers have so far been issued worldwide that credit the mathematical achievements of co-discovers Newton and Leibniz, who fought a years-old “mathematical war,” by accusing each other of plagiarism?

In addition to performance currency (when you deliver upon a product above people’s expectations) and relationship currency (when you take the time to connect, engage, and get to know people in your milieu), you need math currency to make yourself an odd in a sea of evens.

If only math teachers and tutors would implement the “No Calculators Allowed” rule, students would be manually forced to learn the routine or tedious steps in getting the answer to some intermediate step of a problem.
