Problem

The table below shows the ancient Egyptian hieroglyphs that were used to represent different numbers.

For example, the number $32$ was represented by the hieroglyphs $\cap \cap \cap ||$. What number is represented by the following combination of hieroglyphs?

$\textbf{(A)}\ 1,423 \qquad \textbf{(B)}\ 10,423 \qquad \textbf{(C)}\ 14,023 \qquad \textbf{(D)}\ 14,203 \qquad \textbf{(E)}\ 14,230$

Solution 1

The first hieroglyph is worth $10,000$, the next 4 are worth $100 \cdot 4 = 400$, the next $2$ are worth $10 \cdot 2 = 20$, and the last $3$ are worth $1 \cdot 3 = 3$. Therefore, the answer is $10,000 + 400 + 20 + 3 = \textbf{(B)}\ 10,423$
