Commutativity.
no; commutative
The existence of the additive inverse (of ab).
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
A*B=B*A is an example of the commutative property of multiplication.
The given form is ab = ba.This is multiplicative commutative property of equality.
Ab = 25 CD
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
