Taking inspiration from these three digits, March 14 (3/14 in the US date format) is heralded as international Pi Day, first marked by US physicist Larry Shaw in 1988. This year brings a unique opportunity to demonstrate an entirely unnecessary degree of zeal by marking Pi Day correct to nine decimal places on March 14, 2015, at 9.26am 53sec – corresponding to 3.141592653, the first 10 digits of Pi. If you’re too busy this weekend, you could book in July 22 – another way of expressing Pi approximately is the fraction 22/7.

Pi is calculated as the ratio between a circle’s circumference to its diameter. Pi is always the same value, no matter the size of the circle, which makes it an important mathematical constant. The ancient Babylonians calculated Pi as three by taking three times the square of the circle’s radius, later refining the value to 3.125. Click to enlarge. On Pi Day, Celebrate Math’s Enigmas. Photo Manil Suri BALTIMORE — EACH year, March 14 is Pi Day, in honor of the mathematical constant.

On Pi Day, Celebrate Math’s Enigmas

Saturday is the once-in-a-century event when the year, ’15, brings the full date in line with the first five digits of pi’s decimal expansion — 3.1415. Typical celebrations revolve around eating pies and composing “pi-kus” (haikus with three syllables in the first line, one in the second and four in the third). But perhaps a better way to commemorate the day is by trying to grasp what pi truly is, and why it remains so significant. iZone NYC. A.

Videos By Topic. Multiplication Pin Explained. It took me a while to figure out what they did, but it's awesome. We've had some requests to explain how to do this and make it work, so using my super high tech Microsoft Paint program, I'll walk you through how to do this multiplication trick. We'll start with multiplying single digits together. We'll do 3x4. I tried to "color code" each number (I'm sorry to those with color blindness, like my husband...the colors won't help a whole lot, I know). Start with the first number, 3.

Next, go to your second number, 4. Now, you are looking for the intersections of the lines (where they cross): Count all the intersections, and you have your answer: So now, what about multiplying numbers with double digits? Start with the first digit of the first number. Now move on to the second digit in the first number. Now let's move to 12. Then take the second digit of the second number. Now, we need to group the intersections.

Each circle/oval counts as one group. Circle your groups. Circle the groups. Maths Games for KS1. Browse Videos student created videos Videos on Mathtrain.TV Student Tutorials.
