Real numbers in math What are real numbers for a person who doesnt know ANYTHING about math, and had to explain them what real numbers are.

Are real numbers only rational and irrational? if so then do we have to say what are rational and irrational

and please it cant have a lot of math involved in it (even if it sounds silly). Like say I am in uni or maybe you as a graduate of a university you want to explain to your niece, your little brother that is what I want like I know the good hard theorems but he wont get it. 

So i want to simply break it down for someone who wants to know what a real number actually is 

so this is what i have so far

So basically say you are a non math person and this is my explanation would it be valid.
So a real number is basically any number that you can think of, let it be decimal numbers, rational numbers which are just fractions, irrational numbers. Real numbers can range anywhere from $\infty$ to $-\infty$
where $\infty$ is the highest number you can think of in your imagination and $-\infty$ is the lowest number you can think of in your imagination. Like numbers really dont end say the biggest number is $1000000000000000000000000000000000000000$ but there is a number bigger than that like $1000000000000000000000000000000000000000$, or the lowest number you can think of is $-1000000000000000000000000000000000000000$ what about $-2000000000000000000000000000000000000000$, etc real numbers are never ending
If you can write it as a decimal, even if the decimal goes on forever, it's a real number.

If you can write it as a fraction of any two numbers, integers or decimals, or as a power of a positive number (or as a whole power of a negative number), it's a real number.
Real numbers are numbers that are on the real number line,

$x\in\mathbb R \iff -\infty&lt;x&lt;\infty$
