Bool, Double and Int are variables.

Booleans can be 1,0,true,false. 1=true, 0=false
Integers are numbers like 1-5-15-2014
Doubles if I remember it right 1,5-25,42-62,35-14186,25

Integer division is simply a division but the result should be integer.
Mod is again a division, but mod returns, what's left from the DIV division.(I think)

Sorry for my english, you should search google for stuff like that.

at a very basic level i think this is what your looking to know. There are some advanced(ish) technical exceptions to what im saying in this post. But for your first lecture the info below will be what you are trying to understand.

Bool, Int and Double are types of variables.

A variable is a segment of memory assigned by the system to store some type of data at run time.

For reasons unknown to me, systems like to know what kind of data is going to be stored in a variable.
If you use an int variable - the system knows that the data in that variable is an integer
if you use a double variable the system knows that its going to be a double in that variable
if you use a boolean the system knows its going to be a boolean value in the variable - (a boolean (bool) is a variable that has two values, either true or false)
