I am struggling to make this calculator for the past few days. Can you please help me

I want to show the Semesters 1-8, after selecting Number of Semester.

Example, if number of semester 1, then show only Semester 1 (X2)

if number of semester 2, then show Semester 1, Semester 2 (X2, X3)

if number of semester 3, then show Semester 1, Semester 2 (X2, X3, X4)

and so on

Result, if number of semester selected is 1 then show only X2, result – Y1=X2

if number of semester selected is 2 then show, only X2, X3, result – Y1=(X2+X3)/2

if number of semester selected is 3 then show, only X2, X3, X4 result – Y1=(X2+X3+X4)/3

if number of semester selected is 3 then show, only X2, X3, X4, X5 result – Y1=(X2+X3+X4+X5)/4

and so on

Hello.

Use the next formula for your calculator:

fieldset[2].hide();
fieldset[3].hide();
fieldset[4].hide();
fieldset[5].hide();
fieldset[6].hide();
fieldset[7].hide();
fieldset[8].hide();
fieldset[9].hide();
 if(x[1] === 1) {
 fieldset[2].show();
 y[1] = x[2];
} else if(x[1] === 2){
 fieldset[2].show();
 fieldset[3].show();
 y[1]=(x[2]+x[3])/2;
}else if(x[1] === 3){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 y[1]=(x[2]+x[3]+x[4])/3;
  }else if(x[1] === 4){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 fieldset[5].show();
 y[1]=(x[2]+x[3]+x[4]+x[5])/4;
  }else if(x[1] === 5){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 fieldset[5].show();
 fieldset[6].show();
 y[1]=(x[2]+x[3]+x[4]+x[5]+x[6])/5;
  }else if(x[1] === 6){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 fieldset[5].show();
 fieldset[6].show();
 fieldset[7].show();
 y[1]=(x[2]+x[3]+x[4]+x[5]+x[6]+x[7])/6;
  }else if(x[1] === 7){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 fieldset[5].show();
 fieldset[6].show();
 fieldset[7].show();
 fieldset[8].show();
 y[1]=(x[2]+x[3]+x[4]+x[5]+x[6]+x[7]+x[8])/7;
  }else if(x[1] === 8){
 fieldset[2].show();
 fieldset[3].show();
 fieldset[4].show();
 fieldset[5].show();
 fieldset[6].show();
 fieldset[7].show();
 fieldset[8].show();
 fieldset[9].show();
 y[1]=(x[2]+x[3]+x[4]+x[5]+x[6]+x[7]+x[8]+x[9])/8;
}
y[2] = x[1];
