Drefius
A. 7(-2,2)+(4,3)=(-14,14)+(3,3)=(10,17) b. (4,3)+(-2,2)+(7,2)=(9,7) c. [(4,3)-(-2,2)]+(7,2)=[(4,3)+(2,-2)]+(7,2)=(13,3) d. (7,2)-(-2,2)-(4,3)=(7,2)+(2,-2)+(-4,-3)=(5,-3)
b. (4,3)+(-2,2)+(7,2)=(9,7)
c. [(4,3)-(-2,2)]+(7,2)=[(4,3)+(2,-2)]+(7,2)=(13,3)
d. (7,2)-(-2,2)-(4,3)=(7,2)+(2,-2)+(-4,-3)=(5,-3)
