comment Two dice thrown, one comes up 6
It's amazing how few people understand possible outcomes and conditional probability. Pre-kidney is exactly right: the answer is 1/11. Only if the dice were distinguishable, e.g., painted different colors, would the answer would be 1/6.

comment What exactly is a number?
Oops, I forgot to mention quantity as measurement which uses units and leads to quantity as position and/or location, relative zero, fractions of various kinds, and vectors. And infinity as a sort of quantity. Quantity is physical and an amazing concept.

comment What exactly is a number?
Yes. Numbers are precisely the names and shorthand notation that we give to quantities. Quantity is a much richer concept that mere counting. It is capable of direction and/or position as expressed in one dimension as signed numbers and in two dimensions as complex numbers and in all other dimensions though not nicely behaved in all. n-adic numbers are an interesting alternative way to represent negative numbers. Then, of course, there are myriad classes of numbers that are also called "numbers" such as prime numbers etc. Numbers can also be used as labels such as indicators of position etc.

comment What is the single most influential book every mathematician should read?
An intelligent math major who got a PhD from Columbia took an entire year to get through just the first chapter with doing all the problems. A year! Long ago I tried and gave up. It is definitely not an innocent's book.
