Ok, I give you my secret, but don’t tell any body about it ok!
In one formula just contains only 2 letters.
The first letter must be in positive, and the second one must be negative.
So, if you want to write “JASA”, this word is divided into 2 formulas,
namely : “JA” dan “SA”.
Do you know the alphabet? We count the alphabets from A until Z there are 26 letters,
so we give the result 1 for letter A, 2 for letter B and etc, till 26 for letter Z.
So “JA” become :
J = 10 (The first letter must be positive)
A = -1 (The second letter must be negative)
Do you still memorize about this formula in mathematic?
ax2+bx+c=0
Then if we put the word “JA” in this formula the result will be :
(x+10)(x-1)=0
x2-x+10x-10=0
x2-9x-10=0
