Super space Vector space that has Z2 grading E = E+ ⊕ E-
Elements of E+ are called even.
Elements of E+ are called odd.

Element of super algebra A = A+ ⊕ A- a
|a| = 0 a ∈ A+
|a| = 1 a ∈ A-
Two elements of super algebra a, b
a, b ∈ 
Super commutator [ a, b ] = ab – ( -1 )|a||b|ba
Supper commutator satisfies super Lie algebra’s next axioms.
[ a, b ] + ( -1 )|a||b|[ b, a ] = 0
[ a, [ b,c] ] = [ [a, b ], c ] + ( -1 )|a||b|[ b, [ a, c] ]
When [ a, b ] =0, a, b are called super commutative.
