Okay, I'm not really sure what the question is because of all the - - + - + +. It looks like morse code. But I will try to answer it as best I can.
A positive plus a positive is a positive.
A positive plus a negative is a negative.
If you have -4 plus 5, it is the same thing as 5 minus 4. The answer is one!
A negative times a negative is a positive. So -6 x -6= 36!
A negative times a positive is a negative.
And of course a postitive times a positive is a positive.
Now that you've read all of that and practiced really hard to memorize it, I'm going to be mean and give you the EASY way.
I'm actually not being mean, it's just that I remembered it after I typed all of that up.
Ready?
Here it is:
If the signs are the same, the answer is +
If the signs are different, the answer is -
I really hope I helped!

actually it all depends on the problem if it is how you are saying it -++ then the answer would be negative because you got to work from LEFT TO RIGHT. order of operations. PEMDAS.. hope this helps you out.

It depends. If you have -11+2+3=-6 or you could hae -11+5+10=4. So depending on the numbers, -++ could equal a negative or a positive, ++- could equal a negative or a positive. It depends on the numbers used.

my math teacher is brilliant and explained this oo so well...
Okay heres a problem...
(-8)- +3
Okay you owe someone 8 bucks.
Okay so you would rewrite it like this and than SOLVE!
-8 + (-3)
so your answer would be -11.
Easy right?
and when you add two positive numbers it will be positive.
two negatives will equal a negative.
a negative and a two positives depends on which is the biggest
EX
-8 + 3 + -2
it would be -7 because 8 is the bigger number. So it takes its sign.
EX
8 + -3 + 2
it would be +9 because after all the math and stuff 8 was the biggest number so the answer takes its sign.
I'm sorry if its not clear as I was typing it I like oo gosh this pretty hard to understand

It varies. A sample is that -5+1+1=-3, yet -1+1+1=1. It can be either positive or negative.+ plus + will always be positive.A - plus - is always negative. A - plus a + plus a + will vary based on the number.
]
a + plus + is postive and a - + - is a negtive and a -++ is postive.
