if both fractions are negative then add like normal then put a negative sign in front like this:
-6/24 + -8/24 = - 14/24 now simplify. your answer is... -7/12
i hope this helped. (oh yeah, same thing with subtraction)

Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
Why do you flip fractions?
So its easier to add subtract or most commonly multiply
How do you add and subtract improper fractions with different denominator?
he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.
Why do fractions need to have common denominator before you add or subtract them simple answer pleas?
So that you only have to add/subtract the numerator which makes it much easier.
How do you subtract a negative and a negative?
Add the second negative to the first negative, so -1 - -2 = 1
What is the difference between subtracting with regrouping in whole numbers and subraction with regrouping in fractions?
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.
What is negative 40 plus negative 50?
-90 (when you add a negative you simply subtract so -40-50 is -90)
How do you subtract a positive number by a negative number?
A little awkwardly phrased, so I'll answer both ways. To subtract a negative from anything, add its positive. To subtract a positive from a negative, the equation is treated as though you are adding two postives, the result is negative.
How do you add or subtract fractions with unlike denominators?
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
Subtraction with negative fractions?
Subtracting a negative number is the same as adding the positive version. So 3- (-4) = 3+7. The same thing is true of all numbers, including fractions. So just add the fractions like you would normally do.
Adding and subtracting negative and positive numbers?
when youre adding negative numbers, you add them and put a negative sign (ex: -6 + -5=-11) when you add negative and positive numbers(ex: -9 + 7) you subtract the numbers and take the sign of the bigger number (9-7=2, so the answer is -2 because the bigger number, 9, is negative when you subtract 2 negative numbers you add them together and put a negative sign when you subtract a neg. number and a pos. number (ex: -8 - 3) you add the numbers but the 3 becomes negative so the problem becomes -8 + -3. the answer is -11
When you have two negatives do you add or subtract?
When you have two negatives, you add the magnitudes, but since, you have both negatives, the direction of the resultant magnitude is along the negative direction, so you add the magnitude and put the negative sign.
