Solution
To determine the correct product of 22 and 39, let's perform the multiplication:
\[
22 \times 39
\]

\]
2. **Multiply 22 by 9:**
\[
22 \times 9 = 198
\]
3. **Add the two results together:**
\[
660 + 198 = 858
\]
So, the correct product of 22 and 39 is **858**.
**Therefore, the correct choice is:**

Did you know that multiplication has been used since ancient times, dating back to the Babylonians around 2000 BC? They developed a base-60 number system, which is one reason we have 60 seconds in a minute today! Multiplication was a fundamental operation in their trade and irrigation calculations, laying the groundwork for modern mathematics. In real life, understanding multiplication opens the door to various practical applications, especially in finance. For instance, if you’re trying to budget for a vacation, you can multiply the cost per day by the number of days to get a total. Mastering these basic operations makes everyday financial planning a breeze!
