Number Theory

In order to convert this to bae 10, we use a simple trick. 

We multiply every digit in 11021 by a power of 9 increasing from 0. 

So, our answer would be

$(11012)_9 = (1 × 9^4) + (1 × 9^3) + (0 × 9^2) + (1 × 9^1) + (2 × 9^0) = (7301)_{10}$

We multiply the units digit by 9^0 and increase from there on. 

So, our final answer is 7301. 

Thanks! :)
