These street signs are on 8th Street in downtown Los Angeles (#DTLA), California.

The street signs say...

After posting this BARS, MathBabbler noticed that it didn't have a

rsCardinalityEvaldespite having 19 equations. [Note: 19 equations is a lot of equations for a BARS to be initialized with.] Given there are five numbers in these signs, MathBabbler put on his equationeer hat and found the following fiversCardinalityEvals.rsCardinalityEval: 6 / (9 - 7) + 8 / 4 = 5 rsCardinalityEval: (9 - 8) * (7 - 6) + 4 = 5 rsCardinalityEval: sqrt((9 - 4) * (7 + 6 - 8)) = 5 rsCardinalityEval: 6 * 4 / 8 + 9 - 7 = 5 rsCardinalityEval: 6 * 8 - 4 * 9 - 7 = 5 * There are five numbers in these signs.
