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
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
2/5 = 4/10 minus 1/10 is 3/10
negative read this : "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"

(10+9)+(1−1)+(2−2)+(3−1)+(4−4) = 21This is the same equation rewritten: (10+9)+(3−1) = 21This can be done as 1-1, 2-2, 4-4 cancel themselves out.

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.
2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10
2 minus 2/5 plus 1/2 minus 4 = -1.9

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 :)
