Oh honey, let me break it down for you. The expression -x represents the opposite of x, which is usually a negative number because it's moving in the opposite direction on the number line. But hey, if x happens to be 0, then -x would be 0 too. So technically, -x doesn't always have to be negative, but most of the time it is.
A positive number multiplied by a negative number will always result in a negative number.
Yes it can
Yes, a negative number subtracted from a positive number will always be positive. Subtracting a negative number is the same as adding the opposite of the negative number. The opposite of a negative number is always positive. A positive number plus a positive number is always positive.
It is 2700000.
x may not always represent a positive number because there are equations that make a variable a negative number

A positive number multiplied by a negative number will always result in a negative number.
Yes it can
A positive number times a positive number will always get you a positive number A negative number times a negative number will always get you a positive number (same signs will get you a positive number) but A positive number times a negative number will always get you a negative number or A negative number times a positive number will always get you a negative number (different signs will get you a negative number)
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
use a absolute value to represent a negative number in the real world
Yes, a negative number subtracted from a positive number will always be positive. Subtracting a negative number is the same as adding the opposite of the negative number. The opposite of a negative number is always positive. A positive number plus a positive number is always positive.
A positive number is brighter than a negative number. Brightness in astronomy is measured in magnitudes, where smaller (negative) magnitudes represent brighter objects. Positive magnitudes are assigned to dimmer objects.

Always.
For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
