Can you try this with any of your secondary school teachers?
I met my secondary school maths teacher last week and he asked for the direction to Zenith Bank in Maitama. I told him to make a 360 turn, walk for about 1.8 metres (round that up to the nearest tens), you will then see a shop which is perpendicularly to your right, make an obtuse angle turn and you will see the bank at a distance of about the logarithm of 7. Let him feel what I felt as a student during his math class in school.
