In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example:
+10 minus -20 = -10
If the plus sign is smaller than the minus sign, the answer will be a minus.
For example:
-10 minus + 20 = -10
In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example:
+5 x + 2 = +10
-5 x - 2 = +10
-5 x +2 = -10

++ = + +- = - Like signs always give me plus. Unlike signs always give me minus when I multiply! My maths teacher made us learn that! :D
7 (Seven) is the next number in your sequence ! Plus four minus two plus four minus two plus four minus two and so on and so on !
You can make the two numbers 6 plus 4, because it's the same thing. So, 6 minus negative 4 is 10.
a negative minus a negative = a positive. the two negatives put together make a plus sign. example... 5-(-7) = 13
Plus and minus.
They equal a minus and two +'s or two -'s equal a + :)
It would be a minus sign. If the two signs are the same, the answer is positive. If the two signs are different, the answer is negative.
When you have two different signs together (a plus and a minus) the minus takes precedence (the minus "wins"). So, for example, 9 + -3 = 9 - 3 = 6.
If something plus and minus something else make two then the initial value must be 2.
-987 + 654 + 321 = 0 .
3--4 Change those two minus signs into a plus. 3+4=7

No. You may be thinking of the rule that a minus times a minus gives a plus. So -1 x -1 = +1. Or you may be thinking of using two plus signs. E.g. 1 + + 1 This just means 1 plus the positive version of one. This is just one plus one.
well unless its some super-hard math I've never heard of, you change the two minus signs next to each other in to plus signs and go from there. 5+5+6=16 you know, you should be able to figure that out! - + - = + sorry that looks confusing. a minus plus a minus equals a plus! hope this helps!!
Perhaps you mean minus minus one is plus one. Like subtracting (taking away) a debt is equivalent to adding on. If you bank balance is two dollars in the red (debt) if you add 2 dollars, that debt has gone. minus 2 minus minus 2 is zero, same as minus 2 plus 2 is zero.
