Question

is this additive inverse property ? 1 + 2 + 3 = 1 + (2 + 3) is this additive inverse property ? 1 + 2 + 3 = 1 + (2 + 3) @Mathematics

Answer 1

a = a is the identity statement
a+0 = a tells us that zero is the additive identity
a*1 = a tells us that one is the multiplicative identity
a+b = b+a is the commutative property of addition
ab = ba is the commutative property of multiplication
a+(b+c) = (a+b)+c is the associative property of addition
a(bc) = (ab)c is the associative property of multiplication
