Was ist 2/3×(-3y) ?

Hallo,

$$\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{\,-\,}}\left({\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{y}}\right)$$    = $${\mathtt{\,-\,}}\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{y}}\right)$$

Plus  *  Minus  ->  Minus      ;  3  im Nenner kürzt sich  gegen  die  3  in der Klammer

Gruß radix !
