Using Base 10 to Calculate Vortex Sum of Different Number Systems

In this video I show that the vortex digit sum (summing the digits until we obtain 1 digit) for any base number system can be obtained quickly by using the default Base 10 Modulo function available in most calculators. For most number systems we need to first convert to the number to its base 10 equivalent before inputting into the calculator, which we can convert via writing as its powers of 10 addition form. However, for the base 4 number system, since the largest single digit 3 is a factor of 9 (largest single digit in base 10), the base 10 mod function gives the same result without conversion!
