NEGATIVE NUMBERS - Zombies and Survivors
First of all we have two teams, positive numbers, which are represented by living humans, or survivors, and negative numbers, which are then, obviously, the undead, zeds, zombies.
positive numbers negative numbers
Let’s start with an addition word problem. Addition with negative numbers is just comparing, canceling, and letting the bodies fall as they will.
We have seven humans, hiding out in a rickety old warehouse, with a surprisingly large arsenal of shotguns and buckshot. Five ambling undead come stumbling out of the local cemetery that has been rained upon by an unknown chemical that reanimates corpses, most likely created by the government as a chemical warfare agent. Who will survive the inevitable fight?
This would be represented as 7+ -5.
Now, our humans are not trained in combat at all, and whether they are or not, to fit the plot of the math problem, we know that they are incredibly bad at fighting zombies and anyone who kills a zombie ends up getting bitten and must die. As in real life, if there is a zombie attack, it is best to hide and stay out of it, but alas, these are brave, if not foolhardy, little positive humans and so, they are jumping right into this fight.
So, we have 7 humans and 5 zombies. They fight, they bite, they very efficiently kill each other, and two emotionally scarred, but whole and victorious, human survivors are left to kill all of the other humans who have been bitten.
Don't forget the double tap!
Ergo, 7 + -5= 2
If there had been 7 zombies and 5 humans, the zeds would have won and we would have been left with two zombies, or -2, since zombies stand for negative numbers.
If we are adding negative numbers, it results in creating a bigger and more horrifying crowd of undead.
-12+ -17= -29
WAY TOO MANY ZOMBIES!
Subtracting works like infection or cure. This is no longer just grouping and canceling, they are all actively being manipulated (probably by the government again, as that is usually the case).
10 survivors minus 3 zombies. The zombies are being affected by that minus sign. It means those zombies turn back into humans.
10 - (-3)= 13 OMG! They’re CURED! Humans again!
Or -8 -(+5) is the same thing as 8 zombies plus 5 bitten humans. The end result is 13 zombies or -13.
MULTIPLICATION AND DIVISION
Let’s go on to multiplication and division. This is one big biting fest.
Here are the rules:
Multiply or Divide like normal and then figure out which sign it gets using the rules below.
Survivor * Survivor = More survivors
(Fairly straight forward, your survivors bite each other. They may be annoyed but, no zombie bites...no zombies!)
+ * + = +
Zombie * Zombie = More survivors
(How in the world? Well, they're off by themselves, biting each other, so their combined number is equal to the amount of humans they AREN’T biting, which makes more survivors. Or perhaps their own bite cures the zombie plague on those already infected… totally viable.)
- * - = +
Zombie * Survivor = More zombies
(I mean, come on, if any infected biting is going on with humans, the zombies are gonna win)
- * + = -
