Question

Very easy question whoever answers first and gets the answer right get 20 points. The problem is
$27 \times 13$
​

Answer 1

Answer:

your answer is 351: )

Step-by-step explanation:

Have a great day ty!

To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.

If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.

Answer 2

Answer:

$351$

Step-by-step explanation:

$27\times \:13$

Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)

$\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}$

Step 2: Multiply the top number by the bolded digit of the bottom number

$\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}$

Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line

$7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}$

Step 4: Add the carried number to the multiplication

$2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}$

Step 5: Multiply the top number by the bolded digit of the bottom number

$\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}$

Step 6: Multiply the bold numbers

$7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}$

Step 7: Multiply the bold numbers

$2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}$

Step 8: Add the rows. Add zero for simplicity

$\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}$

$81 + 270 = 351$

Therefore 27 times 3 is 351
