This amazing math trick can be used to multiply two digit numbers instantly.
It is important to remember that for this particular multiplcation trick that it is just that - it is very specific and has a few conditions which must be met in order for it to work. First the first numbers must add up to ten, and secondly the last numbers must be the same....so very limited, but cool nonetheless!
