Either.
yes.

In fractions, you can NEVER add or subtract
Depends on the actual numbers.-a-(-b) = -a+bIf a>b the answer's negativeIf aIf a=b the answer's 0
When you have two negatives, you add the magnitudes, but since, you have both negatives, the direction of the resultant magnitude is along the negative direction, so you add the magnitude and put the negative sign.
Either.
yes.
If two negaitve signs occur next to each other in an equation, as in 4 -(-2) then the two negatives becomes a positive and you add the two to get 6. Otherwise, you just do what the equation states: -5 + 3 you add; =-2. -5 - 3 you subtract; = -8
2 negatives make a positive
Yes.
In mathematics, the rule that says "two negatives make a positive" is based on the concept of multiplication. When you multiply two negative numbers together, the negative signs cancel each other out to give a positive result. This rule is consistent with the properties of arithmetic and helps maintain consistency in algebraic calculations.

Multiplying and dividing two negatives does equal a positive. Adding two negatives equals a negative, but subtracting two negatives may or may not equal a positive. Ex. -2 * -4 = 8 -10/-2 = 5 -2+ -4 = -6 -4- -2 = -2 -2- -4 = 2
you got none
On the number line if you subtract a positive you move left. If you add a positive you move right. If add a negative you move left. If you subtract a negative you move right. That is just how I learned it. I don't know a wordy explanation.
