MATH PROBLEM! (HELP)

Question

How many different sandwitche's can you make from 3 types of bread, 2 types of cheese, and 2 types of meat? Assume that only one type of each item is used per sandwich. 

Answer 1

The simple answer for this is multiplication:

3 * 2 * 2 = x

3 * 4 = x

12 = x

 

If you want to visualize it, think of this:

We have 3 breads. each one can hold a type of cheese, and we have 2 of those. That is, for every bread, there's two possibilities,

so 3 * 2 = 6.

Now for each of those sandwiches, we have two types of meat, or for each of our 6 sandwiches, there's a choice of 2 meats.

6 * 2 = 12.
