x¶y means %28x%2Fy%29-x%5E2.  Therefore

2/3¶4/5 means %28%282%2F3%29%2F%284%2F5%29%29-%282%2F3%29%5E2

%28%282%2F3%29%2F%284%2F5%29%29-%282%2F3%29%5E2%22%22=%22%22 

%282%2F3%29%2A%285%2F4%29-%284%2F9%29%22%22=%22%22 

10%2F12-4%2F9%22%22=%22%22 

5%2F6-4%2F9%22%22=%22%22 

LCD = 18

expr%285%2F6%29%2Aexpr%283%2F3%29-expr%284%2F9%29%2Aexpr%282%2F2%29%22%22=%22%22 

15%2F18-8%2F18%22%22=%22%22 

7%2F18
