What would you do if you had time to spare while waiting for the bus during your commute?
Apparently, the folks behind an ad at a bus stop along Bukit Timah think it is the perfect time to do… mathematics.
Reddit user @sixpastfour spotted the ad by the Home Team Science and Technology Agency (HTX), but was “too lazy to solve it”.
Redditors couldn’t wait to flex their math-solving skills on the thread, one even boasting that it was “a piece of cake”.
One Redditor even showed how he got the final answer:
(x2 – 106 + 2808)
= (x – 53)2 + 2808 – 532
= (x – 53)2 – 1
= (x – 53 – 1) (x – 53 + 1)
= (x – 54)(x – 52)
