数学的操作をランダムにする方法

Question

私は基本的に、どのタイプの質問を回答したいのか、また何人に答えたいのか、何を質問しないのかという質問を人々に聞いています。私は、特に加算、乗算、減算などのランダムな数学演算をどうやって解くかという問題を抱えています。ここで私の全体のコードですが、私が助けを求めているのは、3つの操作をどのようにミックスするかを理解する必要があるため、「混在」と言います。

    for i in range(questions):

      prod = beg1 * beg2 

      begAns = input("What is " + str(beg1) + " times " + str(beg2) + "? ") 

      if int(begAns) == prod: 
       print("That's right -- well done.\n")

ランダムに、+のいずれかを選択するには - 、または*と二つの数値に適用：今後の参考のため

import random 
from operator import add, sub, mul 

ops = (add, sub, mul) 
op = random.choice(ops) 

beg1, beg2 = random.randint(1,10), random.randint(1,10) 

ans = op(beg1, beg2)
