### Can negative numbers have factors?

Sure. Take any positive number and find its factors. Then, if
you make
an odd number of the factors negative, you then have a set of
factors
of the negative of the original composite number.
That means that the factors of a negative number are not
'unique'.
Take ' 6 ' for example. Its factors are 1, 2, 3, and 6.
If you make the '1' or the '2' or the '3' or the '6' negative,
then you have
four factors of ' -6 '.
Are there any other ways to make an odd number of them negative
?
I see eight different ways to make an odd number of those four
numbers negative.
So ' -6 ' has eight different possible sets of factors.
Is that weird or what !

### When subtracting negative numbers why does it stay negative?

If you have negative 8 and subtract 3, you keep going
backwards...so you get negative 11. or if you have negative 3
apples, and take away 3, then you have negative 6 apples.
Subtraction of a negative number from another negative number
can be positive
For example:
If you have negative three and subtract negative eight you get
positive five.
-3 - (-8) = 5
