What is a negative plus a positive?
When adding a negative number to a positive number, you are essentially subtracting the absolute value of the negative number from the positive number. The result will have the sign of the number with the greater absolute value. For example, -3 + 5 would be equivalent to 5 - 3, which equals 2.
How do you get the absolute value of a decimal number?
You simply delete the plus or minus sign.
Does a negative number plus a positive number equal a negative?
If the positive number is bigger than the absolute value of the negative number, yes. But if the positive number is smaller, the result is negative. And if the positive number is equal to the absolute value of the negative number, your answer will be 0. The absolute value of a number is the number without the negative sign. So, for example, the absolute value of -3 is 3 and the absolute value of -10 is 10.
