The only number that satisfies this condition is zero. When you subtract zero from any number, you will always end up with the same number. This is because subtraction is the inverse operation of addition, and adding zero to a number does not change its value.
ALL such numbers will be multiples of 9.
Six-and-a-quarter
It was an equation to start with. That is, both sides were equal. So, if you do the same thing to each side they will still be equal. You can also add or subtract the same number from each side and they will be equal. As long as you treat both sides the same they will remain the alike -- that is, they will remain equal.
it stay the same when you subtract fractions and when you add fractions.

Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly
Using algebra the number works out as 25
It's the same as adding a positive number.
If the two bottom numbers are the same, you will carry that same number over to the denominator in the answer. To get the numerator (top number) simply subtract the two numerator and place the number over the answer denominator.
'Zero' and any other number.
ALL such numbers will be multiples of 9.

To subtract a positive number, you go the specified number of units to the left. To subtract a negative number (which is the same as adding the corresponding positive number), you go to the right.
Pick a number between 8 and 20. double that number. subtract 16 from that answer. Multiply that result by 4. Divide that total by 8. add 15 to that answer. subtract the number that you started with.
nothing, keep the exponents the same, remember you can only add or subtract when the exponents are the same
When you subtract a negative number, that is the same thing as adding a positive number, so this equals 10.
Yes, it is required to figure out some equations.
