Example:
-4-(-3)=?
Change the subtraction sign to plus sign and change the negative three to a positive three.
-4+3= -1
(-10) - (-5) = (-5) when subtracting a negative number from another negative number if the first number is larger that the second number then you just subtract the to numbers. don't worry about the signs just subtract the numbers when your done put the sign of the first number on again.
When working with negative numbers, you typically start with the number that represents the value you are calculating. If you are adding or subtracting, you consider the signs of both numbers. For example, when adding a negative number, you effectively subtract its absolute value from the other number; when subtracting a negative number, you add its absolute value. Therefore, the process depends on the specific operation being performed.
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.
-- write the difference between the numbers without regard for their signs -- give the difference the same sign as the original number with the greater size
When adding or subtracting a negative and a positive number, you treat it as two separate operations. First, you find the difference between the two numbers ignoring the signs. Then, you assign the sign of the larger number to the result. For example, when adding -5 and 3, you find the difference (5) and assign the negative sign to get -2 as the result.

e.g. 'a' - ( -a) becomes a -- a a + a = 2a Here with a table for manipulating 'double' signs. = + = - = - = + NB If no sign is shown in front of a number , then read the number as plus(O).
Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"

If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.
OVER 9000!
We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.
It's the same thing as solving an equation, the minor difference is to change the inequality sign when the numbers change signs(i.e negative to positive to negative).
