.class expected? Double inside a for

Question

I'm trying to assign a random number to a double inside a for loop, but my compiler doesn't seem to like it. It's saying '.class expected' and 'not a statement', I was wondering if anyone would be so kind as to take a look at my code and give me some direction in what I'm doing wrong? I'm very new to java so I apologise if I'm a little slow on catching on. :)
import java.util.Scanner;
class Classroom {
  public static void main(String args[]) {
    Scanner gavroche = new Scanner(System.in);
/*Gather Information*/
System.out.print("What is your name? ");
String name = gavroche.next();
System.out.print("What grade are you in? ( 1-7 ) ");
int grade = gavroche.nextInt();
System.out.print("What type of test do you want to do? ( +, -, x, / ) ");
String type = gavroche.next();
/*Grade 1 test*/
if (grade == 1) {
/*Addition test*/
if (type.equals("+"))
     System.out.println("Hello " + name + "!");
     for (int number = 0; number < 10; number++)
     double var1 = (int)(1+Math.random()*10);
     double var2 = (int)(1+Math.random()*10);
     System.out.println("What is " + var1 + " + " + var2 + "?");
     int answer = gavroche.nextInt();
     if (answer == var1+var2)
          System.out.println("Correct!");
     else if(answer != var1+var2)
          System.out.println("Wrong!");
}Thank you!

Braces where? It compiles fine without the two double var1 and var2.Yeah maybe. But the logic is all wrong.
Try this formatting for starters
import java.util.Scanner;
public class Classroom {
  public static void main(String args[]) {
    Scanner gavroche = new Scanner(System.in);
    /*Gather Information*/
    System.out.print("What is your name? ");
    String name = gavroche.next();
    System.out.print("What grade are you in? ( 1-7 ) ");
    int grade = gavroche.nextInt();
    System.out.print("What type of test do you want to do? ( +, -, x, / ) ");
    String type = gavroche.next();
    /*Grade 1 test*/
    if (grade == 1) {
      /*Addition test*/
      if (type.equals("+")){
           System.out.println("Hello " + name + "!");
           for (int number = 0; number < 10; number++){
             double var1 = (int)(1+Math.random()*10);
             double var2 = (int)(1+Math.random()*10);
             System.out.println("What is " + var1 + " + " + var2 + "?");
             int answer = gavroche.nextInt();
             if (answer == var1+var2){
                  System.out.println("Correct!");
             }else if(answer != var1+var2){
                  System.out.println("Wrong!");
}
