Is ( + ) - ( - ) = (-) always, sometimes or never true?

Question

please give me some examples to support the answer.

Answer 1

it's NEVER true:

(+) - (-) = (+) Always

e.g:
+5 - (-1) = +5 + 1 {because (-)(-) is always (+)}
= +6

if u remember the rule: (-)(-) = (+) it'll get u through

Answer 2

Never true...

Subtracting a negative is the same as adding a positive.

When you add two positive numbers you have to get a positive and can't get a negative ever.

5 - (-7) = 5 + 7 = 12
5 - (-2) = 5 + 2 = 7
1 - (-1) = 1 + 1 = 2

No way to get a negative. Never, no way, no how.

Answer 3

are you asking if a positive number times a negative number ALWAYS negative? YES :)

5*(-1) = -5
8*(-2) = -16
1*(-1)=-1

oh...sorry you were asking if a positive number minus a negative number ALWAYS negative? NO :)

it isn't...b/c subtracting a negative number is really adding that number...adding a number to a number that is already positive gives you a positive number always

Answer 4

subtracting a negative value is equivalent to adding a positive value, so the above is never true. the only exception is with 0, which is neither positive or negative.

Answer 5

(+) - (-)
(7)- (-9)
7+ +9
=16
I changed my sign for subtracting and adding integers. Though it could be sometimes true but not always just depends on your numbers.

Answer 6

(6) - (-6) = 12

because two negatives together always make a positive so according to your statement it is never true

Answer 7

never

5 - (-3) = 8
