Digital Century

Place exactly three common mathematical symbols between the digits

1 \hspace{0.1in} 2 \hspace{0.1in} 3 \hspace{0.1in} 4 \hspace{0.1in} 5 \hspace{0.1in} 6 \hspace{0.1in} 7 \hspace{0.1in} 8 \hspace{0.1in} 9

so that the result equals 100. The same symbol can be repeated if you wish, but each repeat counts towards your limit of three. Rearranging the digits is not permitted.

Have fun 🙂

More fun later,
