During this first unit (Numbers) I particularly remember learning about prime numbers, prime factorization, number systems, and radicals. When I first started learning about prime factors and prime factorization they were linked together, in a way as a category. Prime factorization is used to find the prime factors of a composite factor, which means that the product of the prime numbers will equal the number we first started out with in the beginning. Prime factorization was a new concept for me, or just a concept that I needed a lot of review with; I first learnt how to use a prime factorization tree (which was completely new to me) this method helped me a lot to find prime numbers and prime numbers are numbers with only the factors of 1 and itself. After learning the basics we then moved onto number systems to be able to know irrational/rational numbers, how to convert into decimals and/or fractions, and overall these lessons would help in the future because I would be able to use the systems for radicals. The last lessons I really learned something new or reviewed were with radical. I learned new terminology such as: index, radicand, radical sign, etc. With the radicals unit I learned about a mixed radical:
