### Jesus the Messiah? What are the odds, mathematically?

December7

What are the Odds? Professor of mathematics, Peter Stoner (June 16, 1888 – March 21, 1980), gave 600 students a math probability problem that would determine the odds for one person fulfilling eight specific prophecies. (This is not the same as flipping a coin eight times in a row and getting heads each time.) First […]

### It’s Christmas and Santa Delivers

December21

Philip Bump, in an article published in The Atlantic in 2011, calculated whether it was possible for Santa (the real one) to deliver presents to all the Christian children in the world. He wrote, “Over the course of one night, St. Nick has to stop by the home of every Christian child in the world. […]

December29

It does seem strange to be sweltering here in summer heat and wanting to have a swim at the beach, while our Northern Hemisphere friends are fighting off cold, winter blasts, and snow. I really enjoyed this blog entry on the Wondrous Mathematics of Winter: “There’s the snowman: the human form given in three spheres. […]

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
