I'm a computer science teacher.  I offered this problem to my students for extra credit.

If you have a magic bag containing and infinite amount of magnetic letters, numbers and symbols as ("A-Z", "0-9", with "+", "-", "/" & "=") in six colors (red, orange, yellow, green, blue and purple) and you want to pull one item out of the bag each second until you have one of each letter, number and symbol in each of the six colors, how long will it take to complete your set?

Note:
There are 40 different shapes, each in 6 different colors, in the bag.
There is no multiply sign because you can use either the "X" or the "+".

Explain your answer.
