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 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.

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