Question

Each letter a, b, c here stands for a number.

$$\begin{gathered} \begin{array}{ccccc}& & \mathrm{a}& \mathrm{a}& \mathrm{a}\\ & \times & \mathrm{a}& \mathrm{a}& \mathrm{a}\\ & & \mathrm{a}& \mathrm{a}& \mathrm{a}\\ & \mathrm{a}& \mathrm{a}& \mathrm{a}& 0\\ \mathrm{a}& \mathrm{a}& \mathrm{a}& 0& 0\end{array} \\ \overline{\underline{\mathrm{a}\mathrm{b}\mathrm{c}\mathrm{b}\mathrm{a}}} \end{gathered}$$

Take a = 1, then find what the numbers b and c will be.

Answer 1

Thus, we get
b = 2
c = 3
