Question

Perform the following subtraction and check your result by corresponding addition :

$7839-983$.

Answer 1

We know the property of subtraction of the whole numbers that if $a,b$ and $c$ are the whole numbers such that $a-b=c$, then $b+c=a$.

Let us perform the given subtraction and check the result by corresponding addition :

Step - $1$: Performing subtraction :

$$\begin{gathered} \frac{7839 \\ -983}{6856} \end{gathered}$$

Step - $2$: Checking the result :

$$\begin{gathered} \frac{6856 \\ +983}{7839} \end{gathered}$$

Hence, on subtracting and checking, the required result is $6856$.
