Answer 1

あなたは両方の質問のためにAとBを使用していますが、それぞれに異なる変数を使用して、それらを個別に確認する必要があり

。

var A = 1000 
 
var B = 1000 
 
var C = 2000 
 
var D = 1000 
 
document.writeln(" <p> Q1 - What does " + A + " + " + B + " equal?</p>")   
 
document.writeln(" <p>Q2 - What does " + C + " + " + D + " equal?</p>") 
 

 
function checkAnswer() { 
 
    var answer2 = document.fillin.answer2.value 
 
    var answer = document.fillin.answer.value 
 
    if (answer != A + B) { 
 
    alert("Sorry, " + answer + " does not equal " + A + " + " + B + ".") 
 
    document.fillin.answer.value = "" 
 
    } else if (answer2 != C + D) {  
 
    alert("Sorry, " + answer2 + " does not equal " + C + " + " + D + ".") 
 
    document.fillin.answer2.value = "" 
 
    } 
 
    else { 
 
    location.assign("https://www.google.com"); 
 
    } 
 
}

<form name="fillin"> 
 
answer 1 <input type="text" name="answer" value=""> <br> 
 
answer 2<input type="text" name="answer2" value=""> <br> 
 
<input type="button" name="check" value="Check" onclick="checkAnswer()"> 
 
</form>
