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

27. 2+7=9 then minus 4. Next is plus 8 minus 3. Plus 9 minus 2. Plus 10 (27). Next is minus 1 which would be 26.

2 minus 2/5 plus 1/2 minus 4 = -1.9

2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10

9A:2 - 1 - 1 + 1 - 1 + 3 - 2 + 6 = 7The answer is seven.

if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)

2 plus 2 equals 4plus1 equals 5minus 1 equals 4divided by 2 equals 2plus 8 equals 1010 minus 6 equals 4so it all equals to +_____29so its 29 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1

When you are using non-standard definitions of "plus" and "minus", or of "equal".

3 + 3 - 7 + 2 - 1 + 109 = 109

k = 7 x^4 - 5x^3 + 7x^2 + 3x - 10 = (x + 1)(x - 2)(x^2 - 4x + 5)

1 minus 2 plus 123 times 4 is equal to 491.

The sum of -1 and -1 is -2.

yes you can. You can add and subtract ANY number, negative or positive, even if it is a decimal. For example 1 + 1 = 2 -1+-1 = -2 -1+1 = 0 A minus plus a minus is a minus. A minus plus a positive is a minus.

A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9

A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).

Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.

2 plus 2 is 4 plus 2 is 6 and six minus 1is 5

It is 21/10 minus 1/10 = 20/10 or 2

2/5 = 4/10 minus 1/10 is 3/10

It doesn't. (-1) x (-1) = positive 1 minus x minus = plus

minus 6, plus 3, minus 6, plus 3...

1 + 6 + 9 - 8 + 4 - 5 + 2 + 3 = -6
