Who said mathematics is intangible? We teach children math with physical blocks. Addition, subtraction, multiplication, division, evens, odds, primes, fractions, greater, lesser, and equal all concepts easily demonstrated by physically organizing small blocks that each represent an integer value of 1. 0 and negatives can be easily inferred from those pieces with very little imagination. That is a huge chunk of the building blocks of mathematics including Algebra.

Pythagorean theorem can be proved by physically breaking the triangle into smaller triangles and rearranging, so that adds trig and the xy plane for another huge branch math being physical.

I can tech vectors by waving my arm around in space so scalar is not abstract either.

On and on.
