Lo digo burdamente como para que se entiendaSi me debes 2 pesosY después me pedis 2 pesos masPasas a deberme 4 pesosYo resto 2 veces y multiplico mi deuda O sea Sumo mas deuda.Ahora explicártelo matemáticamente no podriaPor que son axiomas.Es como macriAumenta y aumenta todoY nosotros multiplicamos nuestro pasivo a fin de mes
Miralo de este modo. Estas en un punto (punto cero) y queres ir a Mar del Plata (Punto 400). Si vas 100 Km hacia adelante quedas en el punto 100. Si saliste mal y te fuiste en sentido contrario 100 Km quedarias en el punto -100 (Tomando como referencia el punto cero desde donde partiste)
If we can agree that a negative number is just a positive number multiplied by -1, then we can always write the product of two negative numbers this way: (-a)(-b) = (-1)(a)(-1)(b) = (-1)(-1)ab For example, -2 * -3 = (-1)(2)(-1)(3) = (-1)(-1)(2)(3) = (-1)(-1) * 6So the real question is, (-1)(-1) = ?and the answer is that the following convention has been adopted: (-1)(-1) = +1This convention has been adopted for the simple reason that any other convention would cause something to break.For example, if we adopted the convention that (-1)(-1) = -1, the distributive property of multiplication wouldn't work for negative numbers: (-1)(1 + -1) = (-1)(1) + (-1)(-1) (-1)(0) = -1 + -1 0 = -2As Sherlock Holmes observed, "When you have excluded the impossible, whatever remains, however improbable, must be the truth."Since everything except +1 can be excluded as impossible, it follows that, however improbable it seems, (-1)(-1) = +1.
