I am going to prove to you, using standard algebra, that

**0,99999999999….. equals 1.**

Now I know that if you have even a basic understanding of maths you say: ‘I know for sure that’s not true’, but I will show you otherwise.

So here is the breakdown:

- let’s start by substituting
**0,99999999999…..**with the letter**a**, so

**a = 0,99999999999….. **

That is easy huh?

2. now say 10 times **a** would mean

**10a = 9,99999999999…..**

that is still right, right? I don’t believe that there is any need for discussion here.

3. if we substract **a** from that, of course you have to do that on both sides of the equal sign, we get:

**10a – a = 9,99999999999….. – a**

still a correct formula.

4. 10a – a is of course 9a, so:

**9a = 9,99999999999….. – a**

5. but since a = 0,99999999999 the right side of the formula could be written as 9

**9a = 9**

6. and that means that a must be 1

**a = 1**

7. combining step 1 and step 6 I have proven to you that

**0,9999999999….. = 1**
