Let's look at the problem: $x^2 + x^2$
**Step 1:** Imagine you have 2 groups of $x^2$ blocks.
Group 1:
🟦 🟦 🟦 🟦
($x^2$ blocks)
Add âž•
🟦 🟦 🟦 🟦
($x^2$ blocks)
Group 2:
🟦 🟦 🟦 🟦
($x^2$ blocks)
=
**Step 2:** When we add $x^2 + x^2$, it's like counting two groups of $x^2$. So,
$$x^2 + x^2 = 2x^2$$
**Total box:**
🟦 🟦 🟦 🟦
($x^2$ blocks)
Total:
🟦 🟦 🟦 🟦 🟦 🟦 🟦 🟦
($2x^2$ blocks)
Great job! So $x^2 + x^2$ equals $2x^2$. 🎉🟦 🟦 🟦 🟦 🟦 🟦 🟦 🟦
