對于 exp，該代碼并不總是創建數學上正確的除法。它創建諸如 2/0 等的除法，并且也不接受“1/3”四舍五入的答案，如“0.33”或“0.33333”。我需要在代碼中更改什么？感謝您的幫助和時間。document.getElementById("button1").addEventListener("click", question);var mulDiv = document.getElementById("mulDiv");function question(){var startButton = document.getElementById("button1");var number1 = document.getElementById("number1");var number2 = document.getElementById("number2");var decider = Math.random(); button1.textContent = "New Question";number1.textContent = Math.floor(Math.random()*5);number2.textContent = Math.floor(Math.random()*5); mulDiv.textContent = "/" };document.getElementById("button2").addEventListener("click", answer);function answer(){var num1 = parseInt(document.getElementById("number1").textContent, 10);var num2 = parseInt(document.getElementById("number2").textContent, 10);var answer = parseInt(document.getElementById("userAnswer").value, 10);var feedBack = document.getElementById("feedBack"); if (mulDiv.textContent == "/"){if(answer == num1 / num2) {feedBack.textContent = "right";} else {feedBack.textContent = "wrong";}} };<button id = "button1">Start</button><p><label id = "number1"> </label><label id = "mulDiv"> </label><label id = "number2"> </label> = <input id = "userAnswer" type=text><button id = "button2">Answer</button></p><p id = "feedBack"> </p>

這行代碼：
number2.textContent = Math.floor(Math.random()*5);
生成 0 到 4 之間的隨機數，因為Math.random()返回 0 到 1 之間的數字（不包括 1）。你應該做：
number2.textContent = 1 + Math.floor(Math.random()*4);
這樣最小值將為 1，最大值將為 5。
