You can't. For example if your equation is: 2x+7=12 then you will subtract 7 by itself, then subtract 7 from 12. You then get 2x=5. You will then divide 5 by 2 and you will get x=2.5 as your final answer.
17 + 11 = 28 + 25 = 53 - 12 = 41.

to subtract fractions you must first convert the fractions so that they have the same denominators, then subtract the numerators from each other.example1/11-1/7=common denominator = 771/11 * 7/7 - 1/7 * 11/11(Note: 7/7 and 11/11 are both equal to one so the value of each fraction does not change)7/77 - 11/77(7-11)/774/77Improved Answer:1/11-1/7 = -4/77 because 7/77-11/77 = -4/77

7/12 - 1/4 = 7/12 - 3/12 = 4/12 = 1/3.
It doesn't actually mean difference, but it can be used to get the difference between values. 11 subtract 4 is 7, and 7 is the difference between 4 and 11.

You can't. For example if your equation is: 2x+7=12 then you will subtract 7 by itself, then subtract 7 from 12. You then get 2x=5. You will then divide 5 by 2 and you will get x=2.5 as your final answer.
7 times 6 is 42. If you subtract two, you get 42-2= 40.
