## “One”： the beginning

January 26, 2017

One is the beginning of everything.

> 1 is the first and smallest natural number: we always start counting from number 1.

> 1 has only one factor or divisor:

1 = 1 X 1

> Look at the example:

5 X 1 = 5, 5 ÷ 1 = 5

Conclusion: Any number multiply (or divided by 1) is itself.

> Look at the example: 1 ÷ 2 = 1/2, 1 ÷ 5 = 1/5 etc.

Conclusion: _______________ (we start introduce fraction from here).

> Look at the identity: 1 ^{x} = 1 (no matter what number x is).

Conclusion: ________________.

> 0 and 1 are the only two numbers in a binary system.

> We end the session with an interesting fact:

1 = 0.999 … … … (repeating forever)
