You have to add the additive inverse. To subtract q, you add -q.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
The answer is a rational number.
Do you mean can we subtract one rational number from another rational number and get an irrational number as the difference? I'm not a mathematician, but I suspect strongly the answer is no. Wouldn't this imply that we can sometimes add a rational number to an irrational one, and get a rational number as a sum? That doesn't seem possible.Ans 2.It isn't possible. Proof :-Given two rational numbers, multiply the two denominators.Express each rational in terms of the common multiple.Algebraically add the numerators of the new rational numbers.Put this over the common multiple; there's the result expressed as a ratio.
It is an irrational number.
Subtract and add the sign of the greater number.
You might add (-pi/3), in which case you obtain zero. Or you can choose any other rational number, and subtract that number minus pi/3. For example, if you want the result to be 2, , the number you must add is (2 - pi/3).
reduce
Yes, you can.
If a set is closed under an operation. then the answer will be a part of that set. If you add, subtract or multiply any two rational numbers you get another national number. But when it comes to division, it is closed except for one number and that is ZERO. eg 3.56 (rational number) ÷ 0 = no answer. Since no answer is not a rational number, that rational numbers are not closed under the operation of division.

Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.
If the number has a + sign then you add it, if it has a - sign, then you subtract it.
