Use a calculator if you're too stupid to solve it.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
The English term 'subtract' means 1: take off or away; 2: make a subtraction
Subtract their numerators, and put on top of the common denominator. Thus, for example, 5/3 - 3/3 = 2/3. Works for addition, too (add the numerators).
When one number is subtracted from another number, the result is known as the difference.
