Logical Problem of the day

Using the most powerful telescope ever made, let's call it the Bubble Telescope, just for fun, scientists happen to observe a class of young aliens on a planet millions of light-years away.

So, they look through the telescope and they see aliens in a classroom, millions of light-years away. So, this alien classroom has teachers and students. And on the chalkboard, the scientists can see the following equations are written. 

13 + 15 = 31

10 x 10 = 100

6 x 3 = 24
And the question is, how many fingers do these aliens have?
