Minus a negative means you can plus a positive so therefore the answer would be positive 8.
-8
The sum of 7 and -8 is -1.
Negative plus Negative would equal positive in Maths. like this: -7 + -8 = 1 Because you're adding a minus It Will Not Equal a Positive it will Equal a Negative. -7+-8= -15. Because you are adding a negative to another negative. If the problem was -7+8= 1. Because you are taking seven out of that eight. If It were to be multiplication than a negative TIMES a negative would have been a positive(-8 x -7=56). And a negative TIMES a positive would be a negative (-8 x 7=-56).
+8 plus -4 is essentially the same as 8 - 4. Therefore the answer is four.
Minus a negative means you can plus a positive so therefore the answer would be positive 8.
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)"
a negative times a positive is a negative so 2*-4=-8+10=2
-6 + +8 = +2
-6 + 8 is the same as 8 - 6 is 2
The answer is -3. Simply add the numbers together as you would 2+2 to get the answer. You can use a calculator to check your work.
positive 8 - positive 5 = 8 plus negative 5 8 - 5 = 8 + (-5)
-7 + 15 - 8 = 0
positive 3
If the positive number is greater than the negative, it's a positive. Ex: 8 + (-3) = 5 If the negative is greater though, then the answer is a negative. Ex: 3 + (-5) = -2
-8 + 8 = 0
It could equal both a negagtive number or a positive number. To get a definite positive or negative you times or divide. Well in addition and subtraction negative plus a negative equals a bigger negative. Kinda like -4+-4 =-8, but in multiplication and division 2 negatives equal a positive. -2 times-2 =positive 4.
