if a (+)(+) makes a positive, (-)(-) make a positive (+)(-) make a negative why is -10+7=-3 but -8-3=-11 shouldn't this positive? can someone explain when these terms apply?

Explanation:

-10+7=-3 because 10 i greater and (-)(+)=-

-8-3=-11 because the greatest number is in negative form that's why its not in positive form

Hey there!


Guide:

Negative & negative = positive

Positive & positive = positive

Negative & positive = negative

Positive & negative = negative


For -10 + 7 = -3 it doesn’t give you a POSITIVE because you’re working with a negative (-10) and a positive (7), which it results out to be a negative number (-3)


Whereas, -8 - 3 = -11, it doesn’t also give you a positive because you’re working with a negative (-8) and a somewhat positive (3 or -3 it depends how you look at the equation), it gave you a negative result (-11).


KEEP THAT GUIDE IN MIND WHEN YOURE WORKING WITH INTEGERS, IT MAY HELP ON THE LONG WRONG! :)


Good luck on your assignment & enjoy your day!
