Here's a YouTube video by Don't Memorise that talks about the real number system. Summary Any number that can be put on a number line is a real number. Made using Desmos Integers like −2, rational numbers/decimals like 0.5, and irrational numbers like √2 or π can all be plo...
and thus can be enumerated, will be used on several occasions in the construction of examples. In all the examples and exercises, every infinite subset of R turns out to be either countable or equivalent
The Real Number System
Now construct another irrational number. Let this number have 0 before the decimal point. Add 1 to each digit on the ith position of the ithnumber and write the sum on the ithposition of this new number (if the sum turns out to be 10, we will write 0). In this way, we get the ...

Irrational number, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals 2. A counterpart problem in measurement w
