$$8.5 + 6 + 3 + 6 + 20 + 5 + 4 + 3.5 + 3 - 3 = 56$$

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of $\frac{8}{1}$, $\frac{5}{10}$, $\frac{6}{1}$, $\frac{3}{1}$, $\frac{6}{1}$, $\frac{20}{1}$, $\frac{5}{1}$, $\frac{4}{1}$, $\frac{3}{1}$, $\frac{5}{10}$, $\frac{3}{1}$, and $\frac{-3}{1}$ is $10$. $$\begin{aligned} 8.5 + 6 + 3 + 6 + 20 + 5 + 4 + 3.5 + 3 - 3 &= \frac{8 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 1}{10 \cdot 1} + \frac{6 \cdot 10}{1 \cdot 10} + \frac{3 \cdot 10}{1 \cdot 10} + \frac{6 \cdot 10}{1 \cdot 10} + \frac{20 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 10}{1 \cdot 10} + \frac{4 \cdot 10}{1 \cdot 10} + \frac{3 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 1}{10 \cdot 1} + \frac{3 \cdot 10}{1 \cdot 10} + \frac{-3 \cdot 10}{1 \cdot 10} \\ &= \frac{80 + 5 + 60 + 30 + 60 + 200 + 50 + 40 + 30 + 5 + 30 + -30}{10} \\ &= \frac{560}{10} \\&= 56 \end{aligned}$$
