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

Subtracting negative numbers is exactly the same as adding the positive number.
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.
The negative sign will change to a positive sign when subtracting negative numbers from positive numbers so you will simply add them together.
when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative
If you are subtracting the negative from the positive, the answer will be positive. If you are subtracting the positive from the negative, the answer will be negative.
When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7
Adding two negative numbers will always be negative. Subtracting two negative numbers may be positive or negative. Dividing or multiplying two negative numbers will always be positive.No
-15. The rule is 'subtracting a positive is the same as adding a negative'
Have the second number be greater than the first.
Subtracting two positive fractional numbers, or adding one positive and one negative integer.
Subtracting its additive inverse. (In principle, this is valid for adding positive numbers as well.)
Integers are whole numbers, both positive and negative. Therefore, adding and subtracting integers would be adding and subtracting whole numbers. Examples: 8+2 -8+2 8-2 -8-2
The result of subtracting a negative number minus a negative number can be positive, or negative, depending on which of the numbers is larger. It can even be zero.
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.

How is adding to negative integers the same as and different from subtracting two positive integers?
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
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.
-6-6 is -12. Subtracting negative numbers from each other is like adding positive numbers.
When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive.
subtraction is merely adding a negative number, so subtracting a negative number is adding the negative of a negative number. It should be pointed out that while most people find this concept obvious, it was not obvious to ancient mathematicians. In fact, as late as the 1800s, most mathematicians thought that negative numbers were nonsense.
The result of subtracting 2 numbers is the difference.
When dividing numbers that are different the answer will be negative.
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.
The answer is 22. The rule is "adding a negative is the same as subtracting a positive." - In this case, 41-19=22
It depends on what you are doing to the two identical numbers. If you are multiplying them, it becomes a negative. If you are dividing them, it becomes a negative. If you are adding them, it will always be zero (e.g., 2+ -2 = 0, etc.). There are two ways to subtract. If you are subtracting a positive from a negative, the number remains negative. If you are subtracting a negative from a positive, or a negative from a negative, the negative becomes a positive and you just add from there.
