What is the meaning of $(\\mathbb{Z} n \\mathbb{Z})^{\\times}$? We're left with $\{1,3\}$, so $(\Bbb Z 4\Bbb Z)^\times=\langle\{1,3\},\times\rangle$ What does $\Bbb Z 4\Bbb Z$ mean? From primary school some child might have written something like $$8+7=11$$ A teacher would come to the child and say that he is wrong, and that the answer is $15$ If the child asks why, then the teacher might answer as follows:
arithmetic - Formal proof for $(-1) \times (-1) = 1$ - Mathematics . . . The Law of Signs $\rm\: (-x)(-y) = xy\:$ isn't normally assumed as an axiom Rather, it is derived as a consequence of more fundamental Ring axioms $ $ [esp the distributive law $\rm\,x(y+z) = xy + xz\,$], laws which abstract the common algebraic structure shared by familiar number systems
sql - The column was specified multiple times - Stack Overflow The issue is that your inner query is selecting a type column from both K and L Seeing your inner query selects every column from every table, it will thus have 2 type columns in the result; 1 from K, and one from L

Is there an easy way to return a string repeated X number of times? It uses a base-2 logarithm to find how many times it needs to double the length of the string and then proceeds to do so that many times Since the remainder to be copied is now less than the total length it is copying from, it can then simply copy a subset of what it has already generated
