Inverse Property

What does it mean?


The additive inverse is the opposite of the number. Any number plus its additive inverse equals 0. $$a + ( -a ) = 0$$ The multiplicative inverse is the reciprocal of the number. Any nonzero number multiplied by its reciprocal equals 1. $$a *\frac{1}{a} = 1$$


Note: a cannot = 0
