-10/10
Negative Infinity/10
-10/10
so if it falls under infinity then -1/10 to the infinite number being subtracted making it infinitly negative... ._.
That's why i used absolute. -1 still makes the number infinite
6/10
wats up with the -?
But you see if you subtract from a negative number it stays negative therefore it will always be -infinite instead of +infinite because it was subtracted from the -1/10 instead of added.
|Pointsyougiveme|*infinity
To make it clear for you: |1|=1
|-1|=1
|-1|*infinity=infinity
So far we haven't needed to use the absolute value. What happens when we try to add a negative and a positive number together? That's when we need to use the absolute value! First we write down the number with the largest absolute value. If it's the negative number, write the negative sign down in front of where your answer is going to go, because the answer is going to be negative also. Next write the number with the smaller absolute value below or to the right of the first number. Subtract the two and you have your answer! Remember that if the number with the larger absolute value was negative, you have to put the negative sign on your answer. If the number with the larger absolute value was positive, the answer will also be positive. Below are two examples.
Problem: -10+5
The absolute value of -10 is 10 so this is our larger number.
(Remember the sign since the larger number was negative)
Now subtract the two: 10-5=5
(Since our larger absolute value was negative, add the "-")
Our final answer is: -5
So: -10+5=-5
Problem: 10+(-5)
The absolute value of -5 is 5 so this is our smaller number.
(Forget the sign since the larger number was positive)
Now subtract the two: 10-5=5
Our final answer is: 5 (since we didn't need the sign)
So: 10+(-5)=5
