[math](10 \cdot 2 - 6) : (3^2 - 2) + 7 \cdot ( 4 \cdot 2 - 5) - 6 :3 + (2^2)^3 - 50[/math]

[math](14) : (7) + 7 \cdot (3) - 2 + (4)^3 - 50 =[/math]

[math]2 + 21 - 2 + 64 - 50 = 35[/math]

[math][(\frac{7}{4} + \frac{1}{2}) - (3 + \frac{1}{4}) + (\frac{4}{3} - 3)] + (\frac{1}{6} - 1) =[/math]

[math][(\frac{7 + 2}{4}) - (\frac{12 + 1}{4}) + (\frac{4 - 9}{3})] + (\frac{1 - 6}{6}) =[/math]

[math][\frac{9}{4} - \frac{13}{4} - \frac{5}{3}] - \frac{5}{6} =[/math]

[math][\frac{27 - 39 - 20}{12}] - \frac{5}{6}[/math]

[math]-\frac{32}{12} - \frac{5}{6}[/math]

[math]\frac{-32 - 10}{12} = -\frac{\not{42}^{\not{14}^{7}}}{\not{12}^{\not{4}^{2}}} = -\frac{7}{2}[/math]
