Brunette College offers 4 math classes, 2 science classes, 3 language classes, and 5 art classes. Sylvia needs to sign up for exactly one class in each subject. How many different combinations of classes does Sylvia have to choose from?

120

Step-by-step explanation:

If Sylvia can choose one of each class, then there are 4 ways she can choose the math class, 2 ways to choose the science class, 3 ways to choose the language class, and 5 ways to choose the art class.

Multiplying these, 4*2*3*5 = 120
