Is the set of irrational numbers closed under subtraction?
No; here's a counterexample to show that the set of irrational numbers is NOT closed under subtraction: pi - pi = 0. pi is an irrational number. If you subtract it from itself, you get zero, which is a rational number. Closure would require that the difference(answer) be an irrational number as well, which it isn't. Therefore the set of irrational numbers is NOT closed under subtraction.
Is pi a natural number?
Pi is not a natural number. Natural numbers are just the regular set of numbers used for counting (1, 2, 3, 4, ...). Pi, being not even a whole number, is not natural.
Which Set of numbers is most reasonable for the circumference of a compact disk?
Irrational numbers, since the value will be a multiple of pi.
How many numbers in Pi?
there are infinite numbers in pi
What set does 0 belong to?
The mathematically correct answer is: any set that contains it. For example, it belongs to the set of all numbers between -3 and +2, the set {0, -3, 8/13, sqrt(97), pi}, the set {0}, the set of the roots of x3 - x2 + x = 0, the set of all integers, the set of all rational numbers, the set of all real numbers, the set of all complex numbers.
What are two complex numbers whose product is 10?
The set of complex numbers includes the set of real numbers. The real number system is just with the imaginary part set to 0. example: z = 5 + i0 = 5 So the simple answer would be (2+i0)*(5+i0) = 10, so the complex values (2,0) and (5,0) get the result your looking for. If you want a pair not on the real line then 2*exp(i*pi/4) and 5*exp(-i*pi/4) will do. If you multiply the two complex numbers you get 2*5*exp(i*(pi/4-pi/4)) which is just 10. Since pure imaginary numbers are also part of the set of complex numbers, you could have -2i * 5i, the i's multiplied together yield -1 and multiplied by -10 = 10.
