If the negative number is a bigger number, the answer will be negative. Conversely, if the positive number is bigger, the answer will be positive. -20+10= -10 (larger negative number) -10+20=10 (larger positive number)
Adding negatives is exactly the same as taking away the positive number. Alternatively you can think of it as "imagine both the numbers are positive, add them together. This number is then negative. And you're done".
Adding IntegersTo add integers, one must consider the following two rules to be a successful.If you want to think of it on the number line you start from 0 and when you add a positive number you go that much to the right, and when you add a negative number you go that much to the left. When adding two positive integers, just add like normal. When adding one positive integer, and one negative integer, it is like subtracting a positive number from a positive number. When adding two negative integers, it is like subtracting a positive number from a negative number.
Whichever number is higher you subtract the other one from it, and keep the sign of the higher number
it depends to the value of the number,when the greater value caries the positive sign,your answer must be positive,when it carries the negative sign,your answer is negative.
the same as adding whole numbers. two negatives = negative. two positives = positive, and a negative and positive depends on the absolute value of the greater number.

Because that is the rule. negative * negative=positve positive *negative=negative and vice versa
Subtracting a positive number from a negative number is the same as adding two negative numbers, which is like adding two positive numbers except you're going to the left from zero on the number line instead of to the right. The rule is to add the absolute values (the numbers without the signs) of the two numbers and keep the negative sign. For example, -3 - 5 = (-3) + (-5) = -1 * (3 + 5) = -8.
The rules for dividing negative numbers is the same as multiplying them. A negative number multiplied/divided by a negative number is positive and a negative number multiplied/divided by a positive number is negative.
-15. The rule is 'subtracting a positive is the same as adding a negative'
Rules When Dividing Positive and Negative Numbers:Rule 1: A positive number divided by a negative number gives you a negative number.Rule 2: A negative Number divided by a negative number gives you a positive numberRule 3: A positive number divided by a positive number gives you a positive number.
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
No, the rule for multiplication is much easier than that. If the two numbers have the same sign, then their product is positive. If they have different signs, then their product is negative.
The answer is 22. The rule is "adding a negative is the same as subtracting a positive." - In this case, 41-19=22
positive and positive are positive positive and negative are negative negative and negative is positive
If you do -5+-5 you get -10 which is not a positive number. If you subtract two negative numbers you could get a positive depending on what number you are subtracting. E.G. -5 - -9 =4 which is positive. A good rule a thumb is -- goes up +- goes down.
If I'm not mistaken its 2 of the same type of integer ( negative negative/positive positive ) equal the same type of integer EX: -1 - (-1)= -1 and if the integers are opposite ( positive negative/negative positive ) then its the sign of the higher number EX: -2 - 6 = 4
It is the positive form of the number raised to that power, multpilied by -1 raised to that power.
Possibly, but not definitely. There is no rule that determines the sign of a sum when many numbers are involved.
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
Becuase in the rule of laws of signs, when you multiply or divide a number that is positve by a negative number or a number that is negative by a positive number (same thing), the product/answer will always be a negative number. But when you multiply/divide a positive number by positive or negative by negative, the product/answer will always be positive number E.g: -2 x 2= -4 / 2 x (-2)= -4 -2 -:- 2= -1 / 2 -:- (-2)= -1 E.g: 2 x 2=4 / -2 x (-2)=4 2 -:- 2= 1 / -2 -:- (-2)=1
The rule for subtracting negative numbers is 'when you are subtracting a negative number from a positive or negative, you must always add it.'Example: 3--3 = 3+3 = 6
