MOVING

I am SOOOOO SAD! I am moving blogs. I have found a blogging host that is much easier (even though it doesn't look anywhere near as fabulous!). I had to weigh up between design and convenience and chose convenience.

Calendar Question

Earlier I posted a calendar question. I asked if I was right? Apparently not. Thanks Mr C for commenting and clearing it up.

It's actually not correct (sorry Jacob). It happens every time 1 July falls on a Friday (obviously). This happened in 1949, 1955, 1960, 1966, 1977 and many other dates -- on average, about once every 7 years. The last time was in 2005.

Puzzle

Mr Golan asked the class to see if they could find the sum of the first 50 odd numbers. As everyone settled down to their addition, Julia ran to him and said, "The sum is 2,500." Mr Golan thought, "Lucky guess," and gave him the task of finding the sum of the first 75 odd numbers. Within 20 seconds, Julia was back with the correct answer of 5,625.
How did she do this?
