In den folgenden Formeln kommen immer genau 3 Zahlen vor. Die Fragen lauten: "Was kommt heraus?" - und: "Warum gerade das?"

$17+18+20$

$5\cdot (4+7)$

$7^{2}+6$

$\sum _{i=1}^{2\cdot 5}i$

${\binom {8}{3}}-1$

$n=3;{\binom {6}{n}}+{\binom {7}{n}}$

${\sqrt {{6050} \over {\pi }}}\cdot \int \limits _{x\in \mathbb {R} ^{+}}e^{-{{x^{2}} \over 2}}\,dx$

Gesucht ist die positive Nullstelle des Polynoms $x^{2}+10x-3575$
