5 + 3.

**The reasoning** Addition means combining quantities together. When you have 5 items and add 3 more items, you're finding the total. Think of it practically: If you have ₦5 and someone gives you ₦3, count forward from 5: "6, 7, 8." You now have ₦8 total. Mathematically: 5 + 3 = 8 This is straightforward arithmetic — no tricks, just careful counting or recalling your addition facts. **Why the wrong options tempt you** - **A) 5** — You might pick this if you forgot to add anything at all, just reading the first number. - **B) 7** — This happens if you miscounted by one (maybe you started counting from 5 itself: "5, 6, 7" instead of counting *3 more* after 5). - **D) 10** — You might get this if you multiplied instead of added (5 + 5 = 10), or added an extra number by mistake. **Quick takeaway** Addition means "how many altogether?" — always count forward from your starting number, and double-check you're adding, not multiplying or skipping steps.
