Java math quiz. Keeps tally and scores but doesn't work and keep getting true as an answer

\ simple math quiz for school. needs a tally and how many questions to ask

import java.util.Scanner; import javax.swing.JOptionPane;

int randomNumberDiv = randomNumber1 / randomNumber2;
int randomNumberRem = randomNumber1 % randomNumber2;

questions: limit " + limit);

System.out.print( limit <=10);
  \\ gives answer but with true in front of the answer

\\ question tally
