Math Unit #2 - Patterns And Algebra

In this unit, parts of it are things that I knew already, and parts of them are new ways to calculate. This unit is also a good unit for me to practise to do algebras, and it helped me do algebra very quickly, and how to sometimes do it in less steps. In this unit, we learnt:

1. Vocabulary of algebra
2. Gathering like terms (combining like terms by adding and subtracting like terms)
3. Multiplying pronumerals
4. Indicies/exponents
5. Expanding (multiplying with grouping symbols)
6. Factoring
7. Using algebra

• We learnt how to find patterns and how to use a pattern to solve an equation.

• We learnt 20 definition of algebra vocabularies.

• We learnt combining (adding and subtracting) like terms.

• We learnt how to group/multiply pronumerals.

(12)(3n)=36n   (3a)(bc)=3abc   (3a)a=3a²

• We learnt how to do division of pronumerals.

• We learnt multiplying and dividing pronumerals in one expression in order to simplify it.

• We learnt how to use algebra (like creating an expression for the perimeter of a square).

• We learnt what is a power, what is an exponent, and what is a base.

• We learnt six laws of indices (e.g. subtract the exponent if you are dividing two power with the same base).

• We learnt how to solve an expression with indices with a substitute. We learnt how to simplify multiplications into powers.

• We learnt how to expand and factorize an expression.

• We learnt algebraic fractions.
