The number zero!
Multiplied by itself = 0 x 0 = 0
Added to itself = 0 + 0 = 0!

any number (n) added to zero equals that same number (n). n + 0 = n
Only the number two, as any number added to itself is equal to the number x 2. Technically the number 0 would also qualify, as 0 x 2 = 0 and 0+0=0
-- Nothing happens to it. -- You generate a new number that's ten times the size of the original number. -- The new number has all the same digits as the original number had, in the same order. But the decimal point in the new number is one digit to the right of where it was in the original number.
0.5+0.5= 1.

1, 2 and 3 are the same whether you multiply or add them.
