Simplify them.
Whatever is required by the context of the question. Whether or not the number is negative gives no indication as to whether to add or subtract.
When you subtract one number from another, the result is called the difference. What does your question mean? If by "when two whole numbers are subtracted" you mean that you subtract one whole number from the minuend, and then you subtract another whole number from the difference, then the answer you get is another difference. In effect, you have one minuend and two subtrahends.
That means that you calculate the cubes of two numbers, and then either add or subtract them.
you add the two numbers that r given then you subtract 180 from the number you got and their you go you will have the answer
add? dont you mean subtract?
you take away one of the whole number=then you add or subtract your fractions=
The same way you would add or subtract whole numbers, leaving the denominators alone.
add, subtract, multiply, divide

You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...

If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
In the same way that you subtract and add numbers. Sometimes, though, if the answer is greater than 360 dgrees, you can subtract 360. This is because the angle measure of a whole turn and a bit is the same as the angle measure of the bit.
Word problems have key words, like sum, add, difference, subtract, product, multiply, quotient, divide.
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
the difference
