Here is a riddle: using only addition, how do you add eight 8’s and end up with 1000?
While thinking over the answer, consider how math can be both fun and challenging.
Because math is so intertwined with our daily lives and essential to understanding the world around us, UNESCO designated March 14th as the International Day Of Mathematics in order to highlight the importance of its study.
Why March 14th?
➕Calendar dates can be written in number form, such as “3.14” where 3 represents the 3rd month of the year and 14 represents the 14th day of the month.
➗The number 3.14 is a special number in mathematics with a special name. It is called “pi” and represents the circumference of a circle (i.e. the distance around a circle) divided by its diameter (the distance across).
This year, over 600 activities globally are being held in-person and online through schools, libraries and museums to highlight the theme of “Mathematics For A Better Word” and goals for sustainable development.
An inspirational example of what can be achieved comes from Sir Isaac Newton. While a student at Cambridge in England in 1661 Newton was thinking about gravity. There was an outbreak of the bubonic plague and schools closed for 18 months. In that short time, while in the countryside waiting for the disease to pass, Newton developed the mathematics of infinitesimal calculus and applied it in identifying the formula to describe earth’s gravity as well as planetary motion around the sun.
Not all of us may be so productive during the current Covid-19 pandemic. Still, much fun and knowledge may be gained by viewing videos and participating in activities organized on the International Day of Mathematics website.
