Well, to begin with you could

Please learn to use code tags, they make reading and commenting on source code MUCH easier.

How to use code tags: http://www.cplusplus.com/articles/jEywvCM9/

There are other tags available.

HINT: you can edit your post and add code tags.

Some formatting & indentation would not hurt either

As formatted:

#include <iostream>

using namespace std;

int main() {
	int Num1, Num2, compAnswer, userAnswer;
	char op;

	// Initialise random seed
	srand(time(NULL));

	// Generate random numbers
	Num1 = rand() % 63 + 1;
	Num2 = rand() % 63 + 1;

	// Generate random operator
	int opNum = rand() % 4;
	if (opNum == 0) {
		op = '+';
		compAnswer = Num1 + Num2;
	} else if (opNum == 1) {
		op = '-';
		compAnswer = Num1 - Num2;
	} else if (opNum == 2) {
		op = '/';
		compAnswer = Num1 / Num2;
	} else {
		op = '*';
		compAnswer = Num1 * Num2;
	}

	// Output equation
	cout << Num1 << " " << op << " " << Num2 << endl;

	do { // Loop
		// Input answer
		cout << "What is your answer: ";
		cin >> userAnswer;

		// Check if answer is wrong
		if (userAnswer != compAnswer) {
			cout << "Incorrect!" << endl;
		}
	} while (userAnswer != compAnswer); // Keeps looping while answer is wrong

	cout << "Correct!" << endl;
}

As a starter then perhaps something like this (using C++ random rather than c rand):

#include <iostream>
#include <random>
#include <iomanip>

std::mt19937 rng(std::random_device {}());

int main() {
	std::uniform_int_distribution<int> nums(-64, 64);
	std::uniform_int_distribution<unsigned> oper(0, 3);
	unsigned correct {}, asked {};
	char again {};

	do {
		const auto Num1 { nums(rng) };
		const auto Num2 { nums(rng) };

		if (Num1 == 0 || Num2 == 0)
			continue;

		int compAnswer {};
		char op {};

		switch (oper(rng)) {
		case 0:
			op = '+';
			compAnswer = Num1 + Num2;
			break;

		case 1:
			op = '-';
			compAnswer = Num1 - Num2;
			break;

		case 2:
			op = '/';
			compAnswer = Num1 / Num2;
			break;

		case 3:
			op = '*';
			compAnswer = Num1 * Num2;
		}

		std::cout << Num1 << " " << op << " " << Num2 << '\n';
		++asked;

		int userAnswer {};

		std::cout << "What is your answer (as an integer): ";
		std::cin >> userAnswer;

		if (userAnswer != compAnswer)
			std::cout << "Incorrect!\n";
		else {
			std::cout << "Correct!\n";
			++correct;
		}

		std::cout << "Again (y/n): ";
		std::cin >> again;
	} while (again == 'y' || again == 'Y');

	std::cout << "Asked " << asked << ", correct " << correct << " (" << std::setprecision(2) << std::fixed << correct * 100.0 / asked << "%)\n";
}

Ah, another "I need better code" leech shows up. They get it and then edit their post to remove their original code.

And now the OP has "left the building."
