Not sure if this trick works when you need to add double digits to get to 100. Ex: 86 x 84.

Also I noticed that if the number is a single digit to add to the end of the number , add a zero in front of it,,, for example if the number is 3x1 and you are supposed to add 3 at the end of answer, it’s 03. 😁
