Hello logan693616!
A positive plus a negative will (always, sometimes, never) be negative.
Give an example that proves your answer:
A positive plus a negative will <u>sometimes</u> be negative.
- Suppose, we take a positive number whose value is greater than that of the negative number. While adding them, we'll take the sign of the greater number, which in this case is positive, so our answer will be a positive number. For example, <em>+4 + (-3) = <u>+1</u><u>.</u></em>
- Now, if we take a negative number which is greater than the positive number, the sum of the two numbers will be negative. For example, (<em>-4) + 3 = <u>-</u><u>1</u><u>.</u></em>
- So, the answer can actually depend based on the value of the numbers used.
- Hence, our answer is ⇨ A positive plus a negative will <u>sometimes</u> be negative.
