I'm not a mathematician, but I think those are the only two numbers.

Only 0 and 2.
Let a be any number that both adds and multiplies to the same value.
So a+a=a*a
so 2a=a^2
so a^2-2a=0
so a(a-2)=0
so a=0 OR a=2
No other result works. Since 2-2 is 0 and 0 is 0.

I think thats it. Not sure but lower numbers seem to be the only numbers that can add and equal their value multiplied because the product will be low anyways. Example 100*100=10000 but 100+100=200 because its a high number.
Hope i helped.
