In Marie's class, there are 10 students, and each student needs 3 notebooks.
Marie calculated \(10 \times 3\) by adding \(3+3+3+3+3+3+3+3+3+3\).
Is there an easier way to find the total number of notebooks?
Choose 1 answer
\(3 + 10\)
\(10 \times 10\)
\(1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1\)
\(10 + 10 + 10\)
