2. \( \begin{array}{r}7 \\ \times \quad 3 \\ \hline\end{array} \)

Let's get multiplying! When you take \(7\) and multiply it by \(3\), you're essentially asking how many groups of \(3\) you can make from \(7\). So, \(7 \times 3 = 21\). That's right, the answer is \(21\)! Now, just imagine this in a real-world scenario: if you had \(7\) boxes and each box contained \(3\) apples, how many apples do you have in total? Yup, you've got \(21\) apples to munch on! 🍏🍏🍏
