As you've posted nothing but the question, I'm going to assume you're having trouble getting started.

For task 1, you're asked to declare an int named mathTotal, as well as a bool named isComplete. int and bool are primitive types. Declaring a primitive type requires the following format:

TYPE NAME;

For mathTotal, that declaration would look like this:

int mathTotal;

Declaring the bool isComplete should have the same format.

I hope this helps you get started!

The following passes

int mathTotal = 0;              //variable declaration and assignment.
bool isComplete;                //it might be better to do bool isComplete = false;

for (int i = 5; i<= 25; i++) {      //review for loops if this represents a problem.
  mathTotal += i;               //equivalent to mathTotal = mathTotal + i;  

}
isComplete=true;

There's no point in just completing the challenge. This is very introductory syntax, so you may want to clarify what it was that you were having trouble understanding.
