When you have a negative and positive in math does it become a negative?

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.


How do you know if a number will be positive or negative when adding?

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.

Subtracting a positive number from a negative number?

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.

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


How do you add and subtract negative and postitive numbers?

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.


If your positive and negative number are the same does it become a negative number or positive number?

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.


What is the sign for multiplication and addition?

If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.
