My rule for subtraction is:

• Keep the second number change the subtraction to addition.
• Keep all the numbers the same, change the sign to addition.
• Keep the first number, change the sign to addition and change the sign of the second number.
• Keep the first number, change the sign to addition and keep the second number.
