When adding a negative number and a positive number, the result can be negative or positive depending on the magnitudes of the numbers. Here are the rules for adding a negative and a positive number:

  • If the magnitude of the negative number is greater than the magnitude of the positive number, the result will be negative. For example, $$(-5) + 3 = -2$$.

  • If the magnitude of the positive number is greater than the magnitude of the negative number, the result will be positive. For example, $$(-3) + 5 = 2$$.

  • If the magnitudes of the negative and positive numbers are equal, the result will be zero. For example, $$(-3) + 3 = 0$$.

In general, when adding two numbers with the same sign, the result will have the same sign as the original numbers. When adding two numbers with different signs, the result will have the sign of the number with the greater magnitude.
