A positive plus a negative equal a positive?

Answer 1

+5 + (-2) = +3


That's wat I interpret.

Answer 2

Negative Plus A Positive

Answer 3

NOT ALL THE TIME!

Only when the positive is greater than the negative:

+1 + -5 = -4

+5 + -1 = 4

If the positive and negative are equal, the answer is always = 0:

+2 + -2 = 0

-10 + +10 = 0

Answer 5

Answer 6

Only if the positive integer is greater than the negative

+10 plus -11 = -1
+10 plus -10 = 0
+11 plus -10 = +1

Answer 7

a positive plus a negative equals a positive only if the original positive was larger than the original negative
-6+8=2
-8+6= -2

Answer 8

If the positive is higher than the negative it will be a positive. For example:
-2+5=3

But if the negative is higher than the positive it will be a negative. For esample:
-5+2=-3

Answer 9

WOW - People post pretty authoritative, but wrong answers here:

To 19-20-1-...: If I owe you five dollars and then borrow a further two, how much do I owe you? Seven. But you've got your signs wrong.

If I start with zero dollars, then borrow five from you, I now have (+) five dollars. If I then borrow two more, I now have +5 + 2 = +7 dollars. Positive plus positive. From *your* point of view, you've lost five (-5) then lost two more (-2), so the amount of money you have is your starting amount minus seven:

x -5 -2, or x + -5 + -2.

To faisal: First of all, there's a typographical error in your list of identities. You say that negative plus negative is positive, but then you write the negative sign.

Second, and more importantly, your identities are incorrect. These are actually the properties for the PRODUCT of two numbers.

If x and y are positive, then xy = positive
If x and y are negative, then xy = positive
If x is negative and y is positive, then xy = negative

As far as *addition*, not multiplication, those properties aren't true. Instead:

If x and y are positive, then x + y = z, where z is:
- positive
- further from zero ("larger") than either x or y

If x and y are negative, then x + y = z, where z is:
- negative
- further from zero than either x or y

If x is positive and y is negative, however, there's no one rule.

Say x+y=z:
If |x| > |y|, then z is positive, and closer to zero (smaller) than x
If |x| = |y|, then z = 0
If |x| < |y|, then z is negative, and closer to zero than x

(In case anyone hasn't seen it before, the symbols | | around a number mean "absolute value", or "distance from zero".
So | 4 |=4, and | -4 |=4.)

---

Anyway, that's it. Rajiv and ALOS are basically correct, although ALOS' "larger" refers specifically to the absolute value. Hope this helps!

Answer 10

In Math it is OK... if the positive has greater module than the negative: (+20) + (-10) = +10

But...
( a male) + (a female) can result (a male) or (a female)
and there are no correlation with the size.

Answer 11

In mathematics:
positive plus positive is positve + (+) + =+
positive plus negative is negative + (+) - = -
negative plus negative is positve - (+) - = -
