Each time you subtract zero you will begin and end with the same number - ie, the original amount.

ALL such numbers will be multiples of 9.

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.
Division can be thought of as the opposite of multiplication: 0 ÷ 3 is the same as saying "what number when multiplied by 3 results in 0"; answer: 0. 3 ÷ 0 is the same as saying "what number when multiplied by 0 results in 3"; no number when multiplied by 0 results in 3 (as 0 times anything is 0), thus it can't be done. Alternatively, division tells you how many times you need to, or can, subtract the divisor from the dividend to get to zero. If you start with a dividend of zero and a non-zero divisor, you don't need to, nor can you, subtract the divisor to get to zero. If you start with a non-zero dividend, and a zero divisor, no matter how many times you subtract the divisor you will never get to zero - the dividend stays the same. With a zero dividend and a zero divisor, you have reached zero when you start, BUT you can subtract the divisor and the dividend will then become (stay) zero; thus zero divided by zero is any number you want - in calculus there are rules which specify the value to use in different circumstances.
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
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.
It's the same as adding a positive number.
'Zero' and any other number.
The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
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.
