Given that π is the additive inverse of π, which of the following is true?
00:00:07.640 --> 00:00:26.080
a) π minus π equals zero, b) π minus π equals one, c) π plus π equals zero, d) π plus π equals one, or e) π times π equals one.
00:00:27.440 --> 00:00:28.640
What is an additive inverse?
00:00:29.320 --> 00:00:32.520
Itβs what you add to a number to get zero.
00:00:33.120 --> 00:00:38.560
The additive inverse of π is such that when you add it to π, you get zero.
00:00:39.520 --> 00:00:47.960
Weβre already told that π is the additive inverse of π, and that means π plus π must equal zero.
00:00:48.520 --> 00:00:52.200
It means that π is negative π.
