I found out that you can't ever make a power of 2, so you cant do 2, 4, 8, 16,
32...etc. Also you can always do odd numbers and you can't do even numbers
with just 2 numbers E.G 4= 1+2 doesn't work.

You can't ever do even numbers with just 2 numbers because the nearest
it would ever get to is 1 away.

By multiplying consecutive numbers E.G
