Because minus a negative number is equivalent to plus a positive number. So, in effect, you have a positive number plus a positive number and that is going to be positive.
The result will always be negative. Positive X Positive = Positive Negative X Negative = Positive Positive X Negative = Negative
The way you add a negative number to a positive number is very simple to learn. First you need to check which number is bigger, the negative or the positive. Then you subtract the smaller number from the bigger number. Whichever number is bigger is the sign you keep. If the bigger number was positive your going to put a + in front of the answer. If its negative your going to put a minus sign in front .Here's an example: -5 + +9 = +4
A negative plus a negative is a negative. It's like subtracting a positive number from a negative number, the answer isn't going to be positive.
A negative multiplied by another negative will always give a positive answer. E.g. -4 x - 3 = 12
the number in the root should be a positive number other wise the answer is going to be an imaginary number
Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to be positive. (no matter if there is a positive sign in a math problem).
The sum is less than the positive number. Example: 16 + -3= 13. As you can see 13 is less than 16 so the sum is less than the positive number.
Yes; it is a distance on a number line starting at 0 and going positive only.
You draw a line and place "0" in the middle and mark off units away from the "0" at equal distances. Those going to the left of the "0" are negative, those to the right positive.
