Identify Operation and Signs: Step 1: Identify the operation and the signs of the numbers. We are subtracting two negative numbers: −10 and −7.
Subtracting Negative Numbers: Step 2: Subtracting a negative is the same as adding the positive equivalent. So, −10−(−7) becomes −10+7.
Add Absolute Values: Step 3: Add −10 and 7. Since the numbers have different signs, we subtract their absolute values and keep the sign of the larger absolute value number. ∣−10∣=10 and ∣7∣=7. 10−7=3. The sign of the larger absolute value (−10) is negative, so the result is −3.
