### 14 Jan 2016: Key things we do today...

What we did/ discussed today:
• Revisit what a prime number and a composite number is.
• We looked closer to the presentation of working when carrying out prime factorisation using each method.
• How to tell, from the index notation, if a number is a perfect square or not; which could be extended to others (e.g. perfect cubes)
• How prime factorisation could be used to find square root of a number, which could be extended to other "roots"
Things to follow-up:

Homework

1. a mixed number cannot be a odd or even as the odd or even concept on comes in when the number is a whole number. since an odd number is the number between two even whole numbers, a mixed number is not between two even whole number, mixed numbers cannot be odd.
