Answer 1

There are negative letters.

NO

Answer 2

Addition: once you upload a unfavorable variety, that is like subtracting the effective of that variety, so which you would be able to change the + to a -. case in point: 5 + -3 = 5 - 3 = 2 -5 + -3 = -5 - 3 = -8 (submit to in recommendations, once you subtract from a unfavorable variety, you bypass down: -8 is 3 decrease than -5) -5 + 3 = -2 (when you consider which you're including so which you bypass up) Subtraction: an identical regulations shop on with, you may opposite a subtraction sign right into a plus sign and alter the variety to a unfavorable. in spite of the undeniable fact that, in case you have been subtracting a unfavorable variety, you're able to change it to plus a effective variety, simply by fact the unfavorable of a unfavorable is a effective. 5- -3 = 5 + 3 = 8 -4 - -2 = -4 + 2 = -2 Multiplication: once you multiply a unfavorable by way of a effective, the effect is often unfavorable. once you multiply a unfavorable by way of yet another unfavorable or a effective by way of yet another effective, the effect for the two is often effective. 2 x 3 = 6 -2 x -3 = 6 -2 x 3 = -6 2 x -3 = -6 (which variety is unfavorable does not rely in multiplication like it does as nicely and subtraction) think of approximately it like this. First, that is obtrusive that 2 positives could make a effective, proper? That explains one section. Now evaluate 2 negatives: the two negatives cancel one yet another out, so which you land up with a effective. And once you multiply a unfavorable and a effective, the single unfavorable isn't canceled out so the respond is unfavorable. branch: the regulations for branch are comparable to those for multiplication. If the two are effective or the two are unfavorable, the variety continues to be effective. If one is effective and the different is unfavorable, the respond is unfavorable. -2 / -3 = 2/3 2 / 3 = 2/3 -2 / 3 = -2/3 2 / -3 = -2/3 (as quickly as back, which variety is unfavorable does not rely, in spite of the undeniable fact that, do no longer confuse that with the order of the numbers. in case you probably did unfavorable 3 divided by way of 2, it may be distinctive from 2 divided by way of unfavorable 3.)

Answer 3

Because you can put all the numbers you can think of in a line in exactly one place, including the cero. If you add two numbers and you get cero, you choose a number and its negative. You could do that with letters too but you'd have to say how much each letter is worth. Blackjack players do it with the cards of a deck to know when to gamble. You can do anything you want in math as long as you remember you're making it up with certain rules.
