Not necessarily. The sum of two irrational numbers can be rational or irrational.
You can not add irrational numbers. You can round off irrational numbers and then add them but in the process of rounding off the numbers, you make them rational. Then the sum becomes rational.
Yes. The sum of two irrational numbers can be rational, or irrational.
Rational and Irrational Numbers
Sure; for example, 10 + pi is irrational, 10 - pi is irrational. Both are positive. If you add them, you get 20.

No, the result is always an irrational number. In more advanced math it is possible to add an infinite amount of rational numbers by way of Taylor Series and get an irrational number. This is how numbers like "Pi" and "e" are derived.
Yes. The sum of two irrational numbers can be rational, or irrational.
no
No. The set of rational numbers is closed under addition (and multiplication).
No, but you can add an irrational number and a rational number to give an irrational.For example, 1 + pi is irrational.
yes
If an irrational number is added to, (or multiplied by) a rational number, the result will always be an irrational number.
Yes - if I had an irrational number x, and I added that to the number (7-x), I would end up with 7.If the number is irrational, it can be subtracted from a rational/integer to make another irrational.
An irrational number.
