hehehe nahan ayo kog algebra ug trigo hehehe...atoooot..

Nah. Di gyud ko nahan Mathematics. Lisudan ko gud.

[analog man]

take 3 ko sa uban nako nga subject na mathematics sa engineering, ganahan man gud kaayo ko. mao ako gibalik-balik.

Pili og duha ka number 0 to 9 ayaw isaba....i minus ang dako na number sa gamay, dayon i plus ang....

Unsa gani sumpay ana? Limot man ko oi....cge man ko ana sa gamay pa ko

Prove that 2 = 1 [hehehe..the infamous and very old math trick]

if
A = B

then,
AB = B^2

also,
A^2 - B^2 = A^2 - AB

expanding the equation above,
(A + B) (A - B) = A(A - B)

cancel similar equations on both sides,
(A + B) = A

since A = B, replacing B with A,
(A + A) = A

simplifying the equation,
2A = A

divide both side by A to cancel the variables
2 = 1


learn this trick during my 1st yr in college...can't forget it coz our trigonometry professor gave this puzzle to us and said, who would be the very first to submit within 1hour would be exempted for the Prelim Exam for his subject...hehehe

ang nahibaw.an ra jud nko na trick is to multiply any two number by 11 unya calculate ra sa mind. dali ra au..hehe..
ex. 11 x 11 = 121
add 1+1=2 then put 2 in the middle of 1 and 1.
ako g try ang 3 numbers pro sakit na sa ulo..hehehe

Math is ancient.

actually.... there is a flaw with this solution.
by cancelling similar terms on both sides means that you divide both sides by it, which in this case is...

(A+B)(A-B) = A(A-B)
(A-B)............(A-B)

and in math, there is a rule
you can not divide any number by zero.
Because any number [except for zero] divided by zero is undefined.

since A=B, A-B=0

which makes that statement wrong and unacceptable.

thus 2 != 1.

math is fun.
