4 yo DISCOVERED this Math Formula

**2sq. + 2+3= 3 sq. iow: 4 + 5 = 9**

5sq. + 5+6= 6 sq. iow: 25+ 5+ 6= 36

That is true of all numbers except 1

MYSTERY: HOW did a 4 yo learn to do incredibly complex math without a teacher? He sent me a brief description of a formula he figured out at age 4 and I needed 3 DAYS to figure out what the HELL he was talking about. I posted something from him [see emboldened text above] and got no comment. I doubt anybody understood it.

ARE YOU AFRAID OF SAYING "WE DON'T KNOW"?

What is heresay worth?

When did this wondrous event supposedly happen? Sixty-something years ago? Are you, jb, AFRAID to admit that "We honestly DON'T KNOW what the guy's actual age was at the time since we have no way of knowing if, or to what extent, it morphed into '4' (years of age) via faulty recollection or embellishment"?

The unstated "formula" into which you have successively substituted the constants 2 and 5 for x [see emboldened text above] is merely an "expansion" of the square of the binomial x+1 via the distributive law of multiplication.

(x+1)^{2}=x^{2}+2x+1

or, putting it in the form into which you substituted the constants 2 and 5:

x^{2}+x+(x+1)=(x+1)^{2}

(Let x=2, then 2^{2}+2+3=3^{2}, iow: 4+5=9; let x=5, then 5^{2}+5+6=6^{2}, iow: 25+5+6=36)

It is clear from your false statement, "That is true of all numbers except 1" (it certainly *is* true for "1"), that you have no comprehension of this *extremely* basic bit of algebra. If you can't even grasp this rinky-dink morsel without having it explained to you, how could you *ever*, much less in a mere "3 DAYS", attain comprehension *on your own* of genuinely "incredibly complex" mathematics?

I don't anticipate that you will ever provide it, but I would like to see this so-called "incredibly complex" mathematical formula of which you speak.
