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.

positive is to add and negative is to subtract in math

If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.

Yes. to subtract a negative is to add that number, so the number will be higher than the first number which is positive and can't go below zero.

If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)

It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.

Numbers are positive unless they have a minus sign (-) in front of them, in which case they are negative. As for the sum of positive and negative numbers, just add them up and find out. Add the positive, subtract the negative. It's very logical.

On the number line if you subtract a positive you move left. If you add a positive you move right. If add a negative you move left. If you subtract a negative you move right. That is just how I learned it. I don't know a wordy explanation.

No a positive plus a positive is not a negative its a positive. because um lets say 6+7 there is no negative number so its just like regular adding.

The answer to 3/4+(-1/2)=1/4. That is because when you add a negative number, it is like subtracting a positive number. When you subtract a negative number, it is like adding a positive number.

subtract the small number from big number (without signs) and then add the sign of the larger number to the difference

You may subtract a positive number from a negative number by simply just adding the two numbers, disregarding their signs, and giving the sum a negative sign. For example, if we have to subtract 3 from -5, then you just add 3 and 5 which gives you 8. The final answer must be -8.

The same as with positive ones. Make sure they have the same denominator and add or subtract their numerators.

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

If both numbers are positive, simply add them as you learned in 4th grade. If both numbers are negative,simply add them but add a minus to the answer. If one is positive and the other negative, ignoring the signs,subtract the smaller from the larger and add the sign of the larger to your answer.

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.

That depends on the values of the given numbers but a positive number multiplied by a negative number will be negative

When you add: a negative and a negative: you get a negative a positive and a positive: you get a positive a positive and a negative or a negative and a positive: Subtract the addend with the smaller value from the greater one. If the greater one is positive, your answer will be positive. If the greater addend is negative, your answer will be negative.

You get a positive number because a negative number reverses the other negative so it becomes a positive number.

multiplying and dividing- positive * positive= positive positive * negative=negative negative *negative=positive subtracting- -3-6=? 1. freeze first number- -3 2.reverse the sign to a addition- -3+ 3.Reverse the sign of the number- -3+-6= -9 adding- keep the sign of the larger number, then add/subtract

You subtract smaller number from larger and take sign of the larger For example negative 7 + 4 = -3
