You asked:

Evaluate the expression: \(17 - 3.6 \cdot 2.1\)

MathBot Answer:

\[17 - 3.6 \cdot 2.1 = \frac{236}{25} = 9.44\]

\[\begin{aligned}17 - 3.6 \cdot 2.1& = 17 - \left(3 + \frac{6}{10}\right) \cdot \left(2 + \frac{1}{10}\right)\\& = 17 - \left(3 + \frac{3}{5}\right) \cdot \left(2 + \frac{1}{10}\right)\\& = 17 - \frac{18}{5} \cdot \left(2 + \frac{1}{10}\right)\\& = 17 - \frac{18}{5} \cdot \frac{21}{10}\\& = 17 - \frac{189}{25}\\& = \frac{236}{25}\end{aligned}\]
