Well,
We can see that there are 8 10's and 3 1's. So we can write 8 10's followed by 3 1's and join them with addition symbols.
83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1
I don’t know what I gotta about it wasn’t the best thing to say about
290
There's 2 hundreds = 200
Then you have 9 in the tens digit.
The only possible answer for the one's digit is 0 since 0 + 9 = 9.
So the answer is 290.
