If you may use each of the six digits only once, then you can only have 3 pairs of 2-digit numbers beginning with an odd digit.
e.g.
12 and 34 and 56
or 14 and 36 and 52
or 16 and 32 and 54

There are 4 possible numbers if the digits are not repeated; 18 if they are. Those are 3-digit numbers, assuming that zero would not be a leading digit. If zero is allowed for a leading digit, then you can have 6 for the non repeated, and 27 if repetition.
You have seven different digits (symbols) to choose from, so you can form seven different one digit numbers and 7×7=72=49 different two digit numbers.
