\[ -0.1 + 0.06 = - \frac{1}{25} = -0.04 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{-1}{10}\) and \(\frac{6}{100}\) is \(100\). \[ \begin{aligned} -0.1 + 0.06 &= \frac{-1 \cdot 10}{10 \cdot 10} + \frac{6 \cdot 1}{100 \cdot 1} \\ &= \frac{-10 + 6}{100} \\ &= \frac{-4}{100} \\&= - \frac{1}{25} \end{aligned} \]
