It depends if the negative number is bigger than the positive number your answer will be a negative number/answer for example -9 - 4 your answer would be -5 since the negative number is bigger it will be the other way around for a positive number if the positive number is bigger than the negative number your answer will be positive for example 5 - -2 = 3 or positive 3.
It’s a grouping of linear(straight line)equations that deal with the same variables. Hope that helped?

This is Scientific Notation here's what you have to do:
First find the Notation:
8.23×10^5
It positive so go to the right.
=823000.
Next do the same thing but with the next Notation:
3.19×10^8
Its positive so go to the right:
=319000000.
Then compare the Notation's
823000. and 319000000.
319000000. is bigger than 823000.
So your answer is 319000000. so its United States.
In a polynomial, each constant (regular number) has a degree of 0. For example, 8 is really 8x to the power of 0.
