Not true (I think :~) Multiplying by ten doesn't mean you play games with the symbols you use to write the number with, it means you add it ten times. Multiplying by 10 has the side-effect of "moving the decimal place" but: 1.234 * 10 = 12.340 if you want to keep the same number of decimal places. But this doesn't work if you have an infinite number of decimal places i.e. 9.999... * 10 != 99.999... Brit posted something where he used 1/infinity but you can't do that. Infinity is a concept, not a number.

Yep. For example, say A is the set of all positive, non-zero integers. This is a set of infinite size, of course. Let B be the set of all non-zero integers, positive and negative which is also of infinite size. But for every element in A, there are 2 in B e.g. the number 10 in A corresponds to +10 and -10 in B. So B is twice as big as A. It's a long time since I did any of this but I think to be of "infinite" size means to be uncountable but you can still set up mappings between uncountable sets like the one above and compare their sizes.
