Question

how do you determine if the answer to a problem is negative or positive in division multiplication addition and subtraction

Answer 1

In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25


in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1


in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.

5+ (-5) = 0
5- (-5) = 10

Answer 2

I think the rules the same: n+n=n p+p=p and if its a n+p, the bigger one gets the sign. for example, if its -3+5, it's 2. basically, the negative 3 is another word for subtracting 3 from the 5. so, 3-5=2. another example is if its 3+(-5). this is the trick i made up to do these problems: so, 3-3=0. how much is left from the 5? 2. but its negative, so -2. this took like, 5 minutes to write, so...hope i helped! ;)
