You can answer something like this

#include <iostream>
#include <ctime>


int randRange (int low, int high)
{
    return rand() % (high - low) + low;
}

int main()
{
    int num1, num2;
    int num1user, num2user;
    
    num1=randRange(10, 20);
    num2=randRange(10, 20);
    
    cout << "Please summation the first number ";
    cin >> num1user;
    
    cout << "Please summation the secound number ";
    cin >> num2user;
    
    if( num1==num1user && num2==num2user ) cout << "excellent "; else cout << "wrong answer";
    
    cout << "\n first generated number is: " << num1;
    cout << "\n second generated number is: " << num2;

    return 0;
}
