Why No Irrationals exist, and why pi and 2.71… are rational numbers
Old Math, and their "Lowest Terms Error" although don't tell them-- proved that 1/2 is irrational Re: analyzing why the Ancient Greek proof that sqrt2 is irrational is flawed
Alright, let me get started on the proof that 1/2 is irrational number using the invalid method of Ancient Greeks that sqrt2 is irrational, only because, the method is invalid.
Earlier I showed how a definition of Lowest Term for p/q needed to be extended to include a number in Rationals in decimal representation. So, what is the Lowest Term for 1/2 in 10 Grid, for it would be .1/.2 and then the next lowest is .2/.4, etc etc.
So, let us run through a proof that 1/2 is a Irrational number using the proof method of Ancient Greeks.
Proof:: Suppose 1/2 is Rational. And now, put 1/2 in Lowest terms and it is thus, in lowest terms. But now, taking 2 and dividing it into 1
__________
2| 1.00000.... = .50000.....
and then dividing 2 by 2
_________
2|2.00000..... = 1.0000.....
And now, we have 1/2 in Lowest terms as .5/1.
But now, hold on a minute, let us divide .5 by 2, then 1 by 2, giving us .25 and .5 respectively.
Since we can never get a Lowest Term for the Rational number 1/2, means a contradiction, hence 1/2 is irrational.
So, of course the above is flawed and flawed in the same way the method was used to prove sqrt2 is irrational, when truly sqrt2 is rational.
What went wrong? What went wrong is a bad definition-- Lowest Terms.
The proof that sqrt2 is Rational, simply involves observation for that
In 10 Grid, sqrt2 = 1.42 X 1.42 = 2.0 (oh, you question the 2.0164, you question the "164", well in 10 Grid, the only digits that exist are the ten place value and that is 2.0.
In 100 Grid, sqrt2 = 1.415 X 1.415
In 1000 Grid, sqrt2 = 1.4143 X 1.4143 and on and on.
Sqrt2 and all sqrt root numbers are Rationals. Even pi and 2.71.... are rational numbers.

Apparently there was a second proof, but whether it was known by Euclid, by Archimedes, I rather doubt it.

Is it because two rational sides would cancel out in a square further down the line? And, if so, then the reason this proof is nonrecurring is only because, well, you use a symbol of sqrt2 that cannot commingle with actual numbers. If you call a number a symbol, call it S, call it Y, obviously you cannot get rid of it.

Once we demand that a number in decimal representation or in fractions be forced upon rather than a "just a symbol sqrt2", then the phoniness of the proof is immediately apparent. Because, that forcing demands sqrt2 be written as 1.42 = 142/100 in 10 Grid or written as 1.415 = 1415/1000 in 100 Grid, etc. Writing sqrt2 in a number, then it behaves like all other Rationals, for it is a rational.

nice proof that no irrationals exist, simple fact that all numbers are Decimal represented and thus a denominator of power of 10 Re: analyzing why the Ancient Greek proof that sqrt2 is irrational is a flawed
Now, here is a Commonsense proof that No Irrationals exist. It is not formal, it is not flowery or pilfered with abstractions. It is a proof that an old grandma or grandpa would understand and recognize, even if starting to slow to think in old age. It is a proof that young kids would be proud of owning. For it is a proof that since 3000 years ago, humanity has thought there was something known as "irrational number" and only now, today, realizes that there are no irrational numbers. That irrational numbers was the grand fake of fakeries.
Theorem Statement:: Rational numbers exist, but Irrationals do not exist.
Proof Statement:: Once we are able to have a Decimal Number system we can build all the numbers via Grids and using a math-induction element and adding that element successively to build the numbers. They are all Decimal numbers, meaning that their place-value is established. So that say for instance .003, or 3.14159..... are all rational numbers because, depending on what place value you want to talk about, it is 3/1000 or 314159/100000. In other words, writing a number in Decimal Representation alone, proves the number is a Rational for the denominator is always a power of 10. And since decimal numbers is ALL POSSIBLE DIGIT ARRANGEMENTS, means that all numbers are a Rational. QED
Now, there is one possible exception to this rule or proof. The imaginary number of square root of -1.
Is it even a number? I am going to say it is not a number, because all numbers have to come from Math induction on a induction element, be it 1 for Counting Numbers, be it .1 for 10 Grid, or .01 for 100 Grid, etc etc. So where does that leave us with sqrt -1. I suggest that i is not a number but an angle, a symbol for an angle. What angle is it? Not 90 degree for that is +1. I suggest i = sqrt-1 is the angle 180 degrees that lies in 2nd and 3rd quadrants.
