Woah, This is so cool! Good job! This will help me with Math at the school!

So the negative one is non symmetrical

B+c=90 and total digree 180-90=90

Kab say channel chlaty ho

Thanks for the scare.. lol😂😂

Its only works for the closer numbers to 100

Где он там увидел девять квадратов?

Contar los cuadrados no me da el resultado correcto😮!

Lame

93^2=(100-7)^2 =100^2-2*100*7+7^2=10000-1400+49=8649

√49 =7 , √4+9=13??

Team 9 is the answer 😊😊😊 👇

(C) 9 team 👇✅

Answer is 9

3root(64)=6+4-3=7 is wrong. It is 4. So this is bullshit math.

2√ 343 = 3 + 4 + 3 = 10 - 2 = 8.

Did a kid make this?

Зачем такая многоходовка, когда это решается всё в уме......😅

Strap in everyone, here we go: General multiplication of two two digit numbers: 'AB' x 'CD' = (10A + B) x (10C + D) = 100AC + 10AD + 10BC + DB This always works. it is the foil method. The "trick" showed here boils down to: 'AB' x 'CD' = 100 (AC + D) + BD for this trick to work the results of both formula should be the same 100AC + 10AD + 10BC + DB = 100 (AC + D) + BD We can subtract BD from both sides --> 100AC + 10AD + 10BC = 100 (AC + D) expand the brackets on the left hand side --> 100AC + 10AD + 10BC = 100AC + 100D Subtract 100AC from both sides --> 10AD + 10BC = 100D divide by 10 --> AD + BC = 10D This is the prerequisite for this formula to work. In both examples given the unit digits were the same (i.e. B = D) which would simplify the prerequisite to --> (A + C) x D = 10D --> A + C = 10 But it would also work for 28 x 77 = 7x8 + 100x(2x7+7)= 2156
