Czy ja to dobrze liczę?
\((-4,0)+( \frac{1}{2}, \sqrt{3}) = (-4 \frac{1}{2}, \sqrt{3})\)
\(( \frac{1}{2}, \sqrt{3}) + (5,-6) = (5 \frac{1}{2}, -6+ \sqrt{3})\)
\((-4, \sqrt{3}) * ( \frac{1}{2}, \sqrt{3}) = (-2, -4 \sqrt{3})\)
\((\frac{1}{2}, \sqrt{3}) * (5,-6)= (5 \frac{1}{2} + 6 \sqrt{3}, -3+5 \sqrt{3})\)
\((5,3)*(-2,8) = (-10-24, 40-6) = (-34,34)\)
\((-6,-7)-(-2,1)=(-6+2, -7-1) = (-4,-8)\)
\(\frac{(-4,1)}{(2,-3)} = (-4,1)* (2,-3)do -1 =(-4,1) * ( \frac{2}{4-9}, \frac{3}{4-9}) =(4, -2 \frac{2}{5})\)
