如何使用Python随机生成算数问题

import random
def add():
    a=random.randint(0,10)
    b=random.randint(0,10)
    print(f"{a}+{b}=选修")
    c=input(">")
    if a+b!=int(c):
        print("wrong!")
    else:
        print("right!")

def subtract():
    j = random.randint(0, 100)
    h = random.randint(0, 100)
    print(f"{j}-{h}=必修")
    s = input(">")
    if j - h != int(s):
        print("wrong!")
    else:
        print("riht!")
def multiplication():
    x=random.randint(0,100)
    y=random.randint(0,100)
    print(f"{x}*{y}=选修")
    z=input(">")
    if x*y!=int(z):
        print("wrong!")
    else:
        print("riht!")
def divide():
    l = random.randint(0, 100)
    m = random.randint(1, 100)
    print(f"{l}/{m}=必修")
    o = input(">")
    if l / m != float(o):
        print("wrong!")
    else:
        print("riht!")
i=1
while i<=10:
    i+=1
    add()
    multiplication()
    subtrct()
    divide()
