Math Problem Statement
there are 4 slots: slot A, B, C and D. The numbers 1, 3, 5, and 7 can be put into any of these slots. All numbers must be present in a combination, and they must be in ascending order from each slot For example, a combination could have the numbers 1 and 3 and 5 in slot A, and 7 in slot D. However, you cannot have the numbers 1 and 3 in slot B, 5 in slot D, and 7 in slot A. Another thing to note is if let's say both the numbers 5 and 7 are in slot C, 5 must come after 7 in the slot. How many possible combinations are there?
