Studdy Solution

STEP 1

Assumptions1. We are given a positive number. . The operation of taking the opposite of a number changes its sign. If the number is positive, it becomes negative, and if it's negative, it becomes positive.

STEP 2

First, let's take the opposite of a positive number. Since the number is positive, taking its opposite will make it negative.
Let's denote the positive number as aa. So, the opposite of aa is a-a.

STEP 3

Next, we take the opposite of the result from the previous step. Since the result was negative, taking its opposite will make it positive.
So, the opposite of a-a is (a)-(-a).

STEP 4

implify (a)-(-a).
(a)=a-(-a) = a
So, the opposite of the opposite of a positive number is a positive number.
