Maths Extension

Today, as a part of the year 7 maths extension, we looked at Pascal's Triangle. This was not actually invented by Pascal. The Chinese invented it but Pascal worked on it so it was named after him. He was French.

This is the triangle.

1

1 1

1 2 1

1 3 31

1 4 6 4 1

1 5 10 10 5 1

1 6 15 20 15 6 1

(It keeps on going.)

We also realised that the first line is 11 to the power of 0, the second line is 11 to the power of 1 and ... it keeps on going. With two digit numbers you add it together. Take line 6 for example.

1

5

10

10

5

1

You add it together like this. So 11 to the power of 5 is 161051.

Cantamath 2011!

On Wednesday, the year 7 & 8 Cantamath teams went to CBS Arena to compete against 100+ schools all over Canterbury. Cantamath is a problem solving competition with 20 questions. All teams have 30 minutes to finish. Both teams did exceptionaly well and Ms Lennon lost $20 over a bet against Merrin. Haha. The Year 7s came 6th. Anyways, the people in the team were:
Year 7s: Justine , Edward , Gabriel & Han-young
Year 8s: Rachel, Selena,Rebecca & Matthew
We all had great fun!
