Hallo Junes91,

so darf man die Berechnung    n i c h t  schreiben:   1.500.00 *3 = 4.500.000 / 2=2.250.000

1 500 000 *3/2 = 2 250 000

oder in 2 Zeilen:   1500000*3 = 4500000

                           4500000 / 2 = 2250000

$${\frac{{\mathtt{1\,500\,000}}{\mathtt{\,\times\,}}{\mathtt{3}}}{{\mathtt{2}}}} = {\mathtt{2\,250\,000}}$$

Gruß radix !

lineare Funktion:   f(x) = mx + b

lineare Gleichungen:

$${\frac{{\mathtt{5\,925}}{\mathtt{\,\times\,}}{\mathtt{2}}}{\left({\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{2}}\right)}} = {\frac{{\mathtt{11\,850}}}{{\mathtt{10}}}} = {\mathtt{1\,185}}$$      

Gruß radix !
