describe('Math functions', () => {
test('adds numbers correctly', () => {
assert.strictEqual(add(2, 3), 5);
});

test('handles async operations', async () => {
const result = await multiply(2, 3);
assert.strictEqual(result, 6);
});

test('throws on invalid input', () => {
assert.throws(() => add('a', 'b'), /Invalid input/);
});
});

I don't get it. what's the issue?
