In this video I show that not only is the vortex sum (summing of digits a number until 1 digit remains) is the remainder when dividing by the largest single digit, but this same number repeats indefinitely after the decimal place. For example, 67 v= 6 + 7 = 13 v= 1 + 3 = 4, and 67/9 = 7.44444..., where the remainder is 4/9 and the repeating digit is 0.4444... This is in fact the same for any number system when dividing by the highest single digit. I show that this is due to the infinite loop that arises when dividing by the highest single digit of any number system, since the number after it is always the transition number 10. Fascinating stuff!

![Vortex Math is Based on the Modulo Multiplication Identity
In this video I show that the previous result of multiplying a number and its vortex sum yields the same vortex sum can be written in its equivalent modulo multiplication identity. Since we have already established that the vortex sum of an integer (summing the digits until we get a single digit) is the same as the modulo of that number with the modulus being the base - 1, we can rewrite the vortex sums using the modulo operations. In general, if we have integers A, B, and C, then we have the identity AB mod C = [A·(B mod C)] mod C. Furthermore we can apply this same identity with the integers inside the bracket to also get it equal to [( A mod C)(B mod C)] mod C and [(A mod C)·B] mod C. Pretty epic stuff!

Timestamps:
- Vortex math multiplication as an equivalent modulo identity – 0:00
- 25 * 4 = 100 v= 1 or 25 v= 7 * 4 = 28 v= 1 – 0:38
- (4*25) mod 9 = [4*(25 mod 9)] mod 9 = 1 – 1:59
- Generalize modulo operation to any integer multiple or modulus: (AB mod C = [A(B mod C)] mod C = [(A mod C)(B mod C)] mod C = [(A mod C)B] mod C – 3:00
- Example: A = 11, B = 22, C = 7 – 4:44
- Reason is because modulo operation gives integers, which can just apply the same identity over again – 5:51
– Modulo of a multiplication of integers is the same as the modulo of the multiplication of either or both modulo of the integers – 6:54
