2 steps

The solution you provided is correct.

Identify the numbers and symbols used.
The numbers used are $0, 1, 2, 3, 4, 5, 6, 7, 8, 9$ . All numbers from 0 to 9 are used.
The only mathematical symbol used is addition ( $+$ ).
Calculate the sum.
$9+8+7+65+4+3+2+1+0 = 17+7+65+4+3+2+1+0$ $= 24+65+4+3+2+1+0$ $= 89+4+3+2+1+0$ $= 93+3+2+1+0$ $= 96+2+1+0$ $= 98+1+0$ $= 99+0$ $= \boxed{99}$
The sum is indeed 99, using all numbers from 0-9 and only one type of mathematical symbol.
