What is the rule for subtracting integers? 

Keep the first number the same, change the subtraction sign to addition, and change the sign of the second number to its opposite. After these changes, follow the rules for adding integers. If both numbers have the same sign, add their absolute values and keep the common sign; if they have different signs, find the difference of their absolute values and use the sign of the number with the larger absolute value.
