0 Hi, 02br
00If I were asked this at a job interview, I'd begin by suggesting it's not a well-worded question and asking for clarification. 02br
02br
00'62' is a number that has two digits, '6' and '2'. So can I move the number '62', or just one of its digits? 02br

02br
02br
00 So you would have 2^6 - 63 = 1 02

02br
00Take away the vertical bar from the plus sign and move it in front of the 1 as a minus sign. 02br
02br
0062 - 63 = - 1 02br
02br

00(I wonder if the original riddle is accurately quoted?) 0-
