Step-by-step explanation:
Hello,
Given the original number n.
![\large \boxed{n}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7Bn%7D)
Multiply the number by 9.
![\large \boxed{9n}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B9n%7D)
Add 99.
![\large \boxed{9n+99}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B9n%2B99%7D)
Divide this sum by 9.
![\large \boxed{\dfrac{9n+99}{9}=n+11}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Cdfrac%7B9n%2B99%7D%7B9%7D%3Dn%2B11%7D)
Subtract the original number, n, from the quotient.
![\large \boxed{n+11-n=11}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7Bn%2B11-n%3D11%7D)
Thank you.
