11. “Pathetic” Maths
3,608,528,850,368,400,786,036,725 has 25 digits and divides by 25.
BUT... if you just take the first n digits, the result will divide by n. For example, are the first 6 digits and divides by 6.
1729 is the lowest number that can be expressed as the sum of two cubes in two different ways! In other words, 1729 = OR
If you multiply by 4 it turns backwards.
153, 370, 371 and 407 are all the "sum of the cubes of their digits".
In other words 153 =
19 = 1 × and 29 = 2 ×
This also works for 39, 49, 59, 69, 79, 89 and 99.

12. Math is no more about equations than poetry is about spelling
Math is no more about equations than poetry is about spelling. Equations and spelling exist to convey an idea. Understand that idea.
