Question 345726
<font face="Garamond" size="+2">


For this problem, the universe of number sets that I will use consists of:


Complex numbers


Real numbers


Transcendental irrational numbers


Algebraic irrational numbers


Rational numbers


Integers


Natural Numbers


If you have other sets to choose from, you are on your own there.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ -2.5\ \ ]:  Real, Rational


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3\frac{3}{5}\ \ ]:  Real, Rational


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{25}\ \ ]:  Real, Rational, Integer, Natural


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \pi\ \ ]:  Real, Transcendental Irrational


And just as an 'oh by the way': "Pie" is a prepared food item, generally round in shape, with a more or less flaky crust depending on the qualtity, and, when used as a dessert item generally has a sweet filling often made of fruit, or when used as an entrée or side dish item, generally has some sort of savory filling.  "Pi" is the generally accepted English language equivalent of the 16th letter of the lower case Greek alphabet, frequently rendered as *[tex \LARGE \pi], representing the fixed but transcendental (because it is not a root of a non-constant polynomial equation with rational coefficients)   irrational (because it is not the quotient of two integers) ratio between the circumference of a circle and the diameter of that same circle.

My calculator said it, I believe it, that settles it
