In mathematics, there is a term "countable" which is associated with the counting numbers. A countable set can be placed one-to-one with the counting numbers or a subset thereof. All finite sets are countable. The set of counting numbers (or other sets of the same "size", aka cardinality) are also countable. The later is sometimes referred to as "countably infinite" to distinguish.<quoted text>
In Spanish, it would be 49.
50 in Spanish is "cincuenta."
"Sin cuenta," proounced the same (except in Spain, where the "c" is pronounced like a "z"), means uncountable, which could be taken as an infinite amount.
One less than cincuenta (50) is 49 (cuarenta y nueve in Spanish). So the last number before it goes into infinite is 49.
In Spanish anyway.
I know Buck is going to get into at tizzy over that last. He does get it that it all matters in defining your terms clearly...not in the everyday use of the words.
Sets which have a cardinality larger than that of the counting numbers are termed "uncountable". This refers to the fact the sets are too large to put into a one-to-one correspondence with the counting numbers.
The counting numbers, the integers and the rational numbers are all countable. The real numbers are uncountable.
BTW...one way of defining an infinite set is that the set can be put into a one-to-one correspondence with a proper subset of itself. A proper subset is a subset that does not contain all the elements of the entire set. This distinction is made because the set is defined to be a subset of itself...for reasons of mathematical logic I won't go into here. It is just mathematically convenient to define it that way.
