## 📝 How to Solve These Problems (Explanation):
To multiply two 2-digit numbers:
1.
Break one number into tens and units. For example, 36 = 30 + 6.
2.
Multiply the other number by each part separately.
3.
Add the two results together.
This is called the
distributive property:
> a × (b + c) = (a × b) + (a × c)
You can also use the standard algorithm (vertical multiplication), but breaking it down helps understand the math better — especially for learning purposes.
