You asked:

Evaluate the expression: \(-0.4 - -0.5 - -0.1 \cdot 2\)

MathBot Answer:

\[-0.4 - -0.5 - -0.1 \cdot 2 = \frac{3}{10} = 0.3\]

\[\begin{aligned}-0.4 - -0.5 - -0.1 \cdot 2& = - \frac{4}{10} - - \frac{5}{10} - - \cdot \frac{1}{10} \cdot 2\\& = - \frac{2}{5} - - \frac{5}{10} - - \cdot \frac{1}{10} \cdot 2\\& = - \frac{2}{5} - \frac{-1}{2} - - \cdot \frac{1}{10} \cdot 2\\& = - \frac{2}{5} - - \frac{1}{2} - - \cdot \frac{1}{10} \cdot 2\\& = - \frac{2}{5} + \frac{1}{2} - - \cdot \frac{1}{10} \cdot 2\\& = - \frac{2}{5} + \frac{1}{2} - \frac{-1}{10} \cdot 2\\& = - \frac{2}{5} + \frac{1}{2} - \frac{-2}{10}\\& = - \frac{2}{5} + \frac{1}{2} - - \frac{1}{5}\\& = - \frac{2}{5} + \frac{1}{2} + \frac{1}{5}\\& = \frac{1}{10} + \frac{1}{5}\\& = \frac{3}{10}\end{aligned}\]
