The Scottish Open is using math equations to mark all 18 hole locations

At this weekend’s Scottish Open, golfers better think fast if they want to keep track of what hole they’re on. 

Okay, so the scorecard in their pockets will probably do that work for them. But if you notice groups being exceptionally slow starting on Thursday, it might make sense to blame the math equations that adorn all 18 flags:

A quick glance reveals that the equations range from the simple — "10-9" for the first hole — to slightly more complicated problems. For something like "4^2 – 3", it’s important to remember your order of operations. Go ahead, take a tour through the flags and try to match each with its appropriate hole. The answers are at the bottom of this post.

While this is a fun little twist on a golf event, there’s something kind of funny about these flags. With golf ratings up and down in the post-Tiger Woods era, incorporating more math into the game probably isn’t the answer to keep fans in their seats.

On the bright side, though, at least there’s no algebra. And Bryson DeChambeau will probably love the new flags.

Flag equation answers (from left to right, top to bottom): 4, 5, 6, 1, 2, 3, 16, 17, 18, 13, 14, 15, 7, 8, 9, 10, 11, 12
