Decimal Expansion of Rational Numberby TutorVista2,900 views
Hi Mr Nj,
Thanks for such a great series, these are very helpful. I wonder if the properties for Irrational numbers such as Commutative and Distributive could be proved in an easy manner as you did for fractions?

he is basically saying a Rational number has a repeating set of numbers with a pattern EX. 1/3 is a fraction and as a decimal it would be 0.333333333333 It will continue forever with the SAME PATTERN.
An Irrational number will repeat also BUT it WILL NOT have a pattern EX. 22/7 is a fraction But as a decimal it would be 3.1486..... this is a Repeating decimal But it DOES NOT go by the SAME PATTERN
FYI: I am in 7th grade gifted and we reviewed this a few days ago so it is still fresh on me :)

@hannan4564 He's offering the outline of a wall. It's our job to work-out (with a bit of independent research & study) how all the bricks fit in order to build the wall. It's too time consuming to go into detail, he's trying to cover a whole program.
Thanks nj!

I don't understand:
It says that in the case of M less N, if N is bigger than M (as in 1 less 2) that together they are equal to negative N minus M. If that was the case, wouldn't 1 less 2 be equal to negative 3?
