Problem

If $S = 6\times 10,000 + 5\times 1,000 + 4\times 10 + 3\times 1$, what is $S$?

$\text{(A)}\ 6,543 \qquad \text{(B)}\ 65,043 \qquad \text{(C)}\ 65,431 \qquad \text{(D)}\ 65,403 \qquad \text{(E)}\ 60,541$

Solution

Simplify:

\[S = 60,000 + 5,000 + 40 + 3 = 65,043\]

The answer is $\boxed{B}.$

The previous answer was wrong. The previous answer was $6543$
