Question

Multiply the following: $816$ by $26$

Answer 1

Multiplying first number by ones and tens of second number:

Given product: $\begin{array}{c}816\\ \times 26\\ \_\_\_\_\_\_\_\_\end{array}$

Multiplying $816$ by $6$ ones.

$816\times 6=4896$ ones

Now multiplying $816$ by $2$ tens.

$816\times 2=1632$ tens $=16320$

Adding both the product:

$\begin{array}{c}816\\ \times 26\\ \_\_\_\_\_\_\_\_\_\\ \begin{array}{c}4896\\ +16320\\ \_\_\_\_\_\_\_\_\_\\ 21216\end{array}\end{array}$

$$\begin{gathered} 4896+16320 \\ =21216 \end{gathered}$$

Thus, $816\times 26=21216$
