Connecting Math to Our Lives Report Math Fun Bangalore, INDIA: Math Fun Being a Math teacher, I feel it a pleasure to join this project.Math is usually considered as a tough subject. so, let me start with humour in math. There is this group of 7 friends. They plan an outing by a taxi. So they go to a taxi driver and ask him how much a ride would cost. The driver frets a little and tells them, "Sahab! If only four of you were to be there I would charge you just the meter rate, but then since seven of you would be there, you have to give me Rs. 10/- more." They agree and decide to take the taxi. The taxi driver takes them to destination. The meter shows Rs. 18/-, so the taxi driver says, "You have to pay me Rs. 28/-." Now, they have to share the cost among themselves and so they decide to divide the total (Rs. 28/-) by the number of people, i.e. 7. This is how they do the calculation to arrive at the answer: ____ 7 | 28 = 13 ( 7 x 1 = 7, 7 x 3 = 21 ). 7 -- 21 21 -- 0 -- The driver (naturally) is exceedingly happy upon receiving Rs.13/- from eachone of them. He thanks them profusely and the feeling of exultant happiness is writtern on his face as he leaves them and proceeds his way. Seeing this, they feel that they may have made a mistake.One of them calculates as follows: 13 13 13 13 13 13 13 -- 28 -- i.e. 3+3+3+3+3+3+3= 21 and 21+1+1+1+1+1+1+1=28 so this checks out. He then says, "Yes, it's correct. The other friend calculates in a different way: 13 x7 --- 21 (3x7) 7 (1x7) -- 28 This checks out as well. -- Do you want the addresses of these friends to make money?
