1.Yes;it is all the same. I say this because if you have a two digit number the first will always be in the ‘tens’ and the second in the ‘units’. So the first number will always be a multiple of ten and the second a multiple of 1.eg: the number y x could be anything. But you know that it is 10y and 1x.Therefore, even if it’s reversed it will be the same total (10 + 1) and it will always be a multiple of 11 because it’s 1 +10(11).
2.You notice that if the second digit is higher than the first, the total will be a minus number and the opposite effect if the second number is smaller.
3.You notice that all the ‘tens’ have there own answer, and when the totals of each ten are put in order, they go up in nines. For example any number from 70 to 79 when put through the number trick, total up to 63, numbers from 80 to 89 total to 72 etc.
4.You notice that it is using the the first number trick after they show their solution videos and it has the same effect no matter how many digits there are.
