I met one of my Mathematics Teacher back then in secondary school today, We greeted normal and he asked for a direction to First BANK and I told him make a 360 turn and walk for like 1.8meters then find the coefficient of X using Pythagoras theory & round it up to d nearest tens, u will then see a big Pharmaceutical which is perpendicular to your right, then make an Obtuse angle turn and you will see the bank at a distance of about d logarithm of 7 using 4-figure table to the Anti-Log, that's it sir. He was staring at me like he wanted to say "Your father!!! "m Let him feel what I felt when i was in secondary sch. I think he should be lost by now, like I did then.
