Sixtillion, two-hundred quintillion
It would be some number of wholes, and a second number of ten millionths.
You didn't say what the numbers were but if the negative number was of greater value (for example -2 + 1) than your answer would be negative. But if the positive number had greater value (2 + -1) than your answer would be positive.
I would say: 43 Or 7
This cannot be properly answered because you did not say what place to round it to. For example; nearest whole number, hundreds, tenths, etc.
To say 1-10 in Hawaiian you would say: Ekahi, ho'okahi, Elua, Ekolu, Eha, Elima, Eono, Ehiku, Ewalu, Eiwa.
