Answer
-20.42
Work Step by Step
When subtracting numbers with different signs, begin by subtracting the absolute values of both numbers:
The absolute value of 9.83 is 9.83.
The absolute value of -30.25 is 30.25.
Subtract these two numbers:
30.25 - 9.83 = 20.42
Now, as 30.25 has the bigger absolute value, the sign associated with this original number is the sign that should be used with our total. As -30.25 has a negative sign attached to it, our answer must be negative:
-20.42
