The absolute value becomes negative.
The absolute value of an integer is the value of the integer without regard to its sign. The absolute value need not be an integer.
To find the absolute value of -3.2, you simply ignore the negative sign and take the positive value of the number. In this case, the absolute value of -3.2 is 3.2. The absolute value function essentially measures the distance of a number from zero on the number line, disregarding its direction.
If the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the lesser absolute value from the greater absolute value and keep the sign of the number with the greater absolute value.
