lets say we have the problem 6-3. The answer is obviously three. Imagine a number line depicting this problem. The point starts at 6. SInce you are subtracting 3, you move the point three numbers to the left, ending up with three.

Now, you can apply the same method for -20-5. On the number line, you start at the number -20. Since you are subtracting five, you move 5 numbers to the left, ending up with -25.

Hope that made sense.

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$4443.48\\
P=\textit{original amount deposited}\to& \$2567\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &17
\end{cases}
\\\\\\
4443.48=2567(1+r17)\implies \cfrac{4443.48}{2567}=1+17r
\\\\\\
\cfrac{4443.48}{2567}-1=17r\implies \cfrac{\frac{4443.48}{2567}-1}{17}=r\implies 0.043\approx r
\\\\\\
0.043\approx\cfrac{r}{100}\implies 0.043\cdot 100\approx r\implies 4.3\%\approx r$
