Basic Math Examples

$7.3 \cdot 1.4$

Step 1

Multiply $4$ by $3$ . Place the ones digit $(2)$ in the result line and carry the tens digit $(1)$ . There is one result line for each digit in $1.4$ .

	$1$
	$7$	. $3$
$⨯$	$1$	. $4$
		$2$

Step 2

Multiply $4$ by $7$ and add the carried $1$ . Place the ones digit $(9)$ in the result line and carry the tens digit $(2)$ . There is one result line for each digit in the $1.4$ .


	$7$	. $3$
$⨯$	$1$	. $4$
$2$	$9$	$2$

Step 3

Multiply $1$ by $3$ . Place the result in the next column in the result line. There is one result line for each digit in $1.4$ .


	$7$	. $3$
$⨯$	$1$	. $4$
$2$	$9$	$2$
	$3$

Step 4

Multiply $1$ by $7$ . Place the result in the next column in the result line. There is one result line for each digit in $1.4$ .


	$7$	. $3$
$⨯$	$1$	. $4$
$2$	$9$	$2$
$7$	$3$

Step 5

Add the numbers in each column. In this case, add $2 + 0$ , then place the $2$ in the result line.


	$7$	. $3$
$⨯$	$1$	. $4$
$2$	$9$	$2$
$7$	$3$
		$2$

Step 6

Add the numbers in each column. In this case, add $9 + 3$ , then place the $2$ in the result line and carry the $1$ .


	$7$	. $3$
$⨯$	$1$	. $4$
$2$	$9$	$2$
$7$	$3$
	$2$	$2$

Step 7

Add the numbers in each column. In this case, add $2 + 7 + 1$ , then place the $0$ in the result line and carry the $1$ .


		$7$	. $3$
	$⨯$	$1$	. $4$
	$2$	$9$	$2$
	$7$	$3$
$1$	$0$	$2$	$2$

Step 8

To find the number of decimal places needed in the answer, add the number of decimal places in the multiplier and multiplicand. In this case, there is a total of $2$ , so the answer must have $2$ decimal places as well.

$10.22$
