Subtraction - If change the negative sign to positive and change the second number into its addictive inverse. The sum is the answer
- 3. Multiplication - If you have to multiply with a whole number, you have to multiply the numerator with the whole number. But when you multiply with a fraction, you have to multiply the numerator with numerator and vise versa4. Division - First turn the second fraction into its reciprocal and then divide the answer. Simply if needed
