Cryptofxt10: I do not agree that a number cannot be multiplied by a negative number. For example, if you were to do this : -2 x -7, would you say there is no solution to this? In this case, one only needs to carry out the multiplication operation in two parts 1. between the respective signs of the operands 2. between the absolute values of the operands. When I say absolute values, I mean using them in natural form(as positive numbers). The absolute values of -2 and -7 are 2 and 7 respectively. now we do this: - x - = + 2 x 7 = 14 Putting the two together, we have +14 or simply 14 |
