On the train we had 41 different kinds of cookies. 3 different flavors of cocoa, and 122 candies. How many treats did we have in all?

41 + 3 + 122 = ?

166

To find the total number of treats, you need to sum up the quantities of each type of treat. In this case, you have 41 different kinds of cookies, 3 different flavors of cocoa, and 122 candies. To get the total, simply add up these quantities:

41 (cookies) + 3 (cocoa flavors) + 122 (candies) = 166

So, in total, you had 166 treats on the train.
