1. The problem is to multiply 243 by 43.
2. The multiplication formula is $a \times b = c$, where $a=243$ and $b=43$.
3. Multiply step-by-step:
$$243 \times 43 = 243 \times (40 + 3) = 243 \times 40 + 243 \times 3$$
4. Calculate each part:
$$243 \times 40 = 9720$$
$$243 \times 3 = 729$$
5. Add the results:
$$9720 + 729 = 10449$$
6. Therefore, the final answer is $10449$.
