Example Question #61 : Operations & Algebraic Thinking

$\frac{\begin{array}[b]{r}9\\ \times 2\end{array}}{ \ \ \ \space}$ $\displaystyle \frac{\begin{array}[b]{r}9\\ \times 2\end{array}}{ \ \ \ \space}$

Possible Answers:

$\displaystyle 45$

$\displaystyle 18$

$\displaystyle 36$

$\displaystyle 27$

$\displaystyle 9$

Correct answer:

$\displaystyle 18$

Explanation:

Multiplication can be thought of as repeated addition, or as objects in a group.

$9\times2$ $\displaystyle 9\times2$ means adding $\displaystyle 2$ nine times.

$\displaystyle 2+2+2+2+2+2+2+2+2=18$ and $9\times2=18$ $\displaystyle 9\times2=18$

Or we can think of this as grouping objects. We have $\displaystyle 9$ groups, with $\displaystyle 2$ objects in each group. We can count up the total number of objects, in this case triangles.
