(a+b)^2=a^2+b^2+2ab
(a-b)^2=a^2+b^2-2ab
a^2-b^2=(a+b)(a-b)
(a+b)^3=a^3+b^3+3ab(a+b)
(a+b+c)2=a^2+b^2+c^3+2ab+2bc+2ca
(a-b)^3=a^3-b^3-3ab(a-b)
a+b=b+c
a(b*c)=(a*b)c
(a-b)^2=a^2+b^2-2ab
a^2-b^2=(a+b)(a-b)
(a+b)^3=a^3+b^3+3ab(a+b)
(a+b+c)2=a^2+b^2+c^3+2ab+2bc+2ca
(a-b)^3=a^3-b^3-3ab(a-b)
a+b=b+c
a(b*c)=(a*b)c
