Question

Replace by the correct digit in each of the following:

$$\begin{gathered} 73*74 \\ \underline{*29**} \\ \underline{6*098} \end{gathered}$$

Answer 1

Replacing * in $$\begin{gathered} 73*74 \\ \underline{*29**} \\ \underline{6*098} \end{gathered}$$ ,

We can see from the right,

In $73*74$ the rightmost digit is $7$.

In $6*098$ the rightmost digit is $6$.

And, $6<7$, so we need to perform subtraction.

Thus, we get $$\begin{gathered} 73074 \\ -\underline{12976} \\ \underline{60098} \end{gathered}$$

Hence, subtraction of $73074-12976=60098$.
