The sum of $5 + 3$ is $8$.

Would you like more details or have any further questions?

Here are five related questions to expand on this:

1. What is $8 + 7$?
2. How would you subtract $5 - 3$?
3. Can you calculate $5 \times 3$?
4. What is $15 \div 3$?
5. What is the sum of $5 + 3 + 2$?

Tip: When adding two numbers, it doesn't matter the order you add them (commutative property of addition). For example, $5 + 3 = 3 + 5$.
