Write a function that is named times_ten and accepts a number as an argument. When the function is called, it should return the value of its argument multiplied by 10.

It changes a little depending on what programming language you're using, but in C you could say

int times_ten (int num) {

num = num*10;

return num;

}

Or, in general terms:

Integer Function times_ten (Integer num)

Set num = num * 10

Return num

This is all done assuming the number used as an argument is an integer and that you are returning an integer value, not a decimal. The main thing to notice is that since you have to return a value, you must have two things: a return statement, and a type declaration for the function, otherwise you'll get an error.
