My Math Journal

On Sunday, I went to Johor, Malaysia, to go to my house.  We ate at McDonalds in a shopping mall there.  Then, we received the receipt and I used mental calculation to convert how much we spent in there.  After I did the conversion, my parents compared the price of eating at McDonalds in here and in Singapore.

That is how I can use Mathematics in my life.
