# Lesson 5: Multiplying Polynomial

This week, I have learned how to multiply polynomial. I have learned different methods, however, this is the easiest way to solve.  When you follow step by step, you will gradually understand the rules and the steps to reach the answer. Before we start the calculation, we must learn some vocabularies. Variable: A letter that represents one or more numbers. Algebraic Expressions: Expressions like 2a-b+4. Monomial: A number or a…

# Lesson 4: SOH CAH TOA

This week, I have learned how to solve right triangle problems with SOH CAH TOA. This method can be used to find the missing angle or length. This method is convenient because you can find the answer quickly. SOH CAH TOA SOH CAH TOA is a rule for determining the sine, ratio, cosine ratio and tangent ratio for an angle in a right triangle. In a right triangle, there are…

# Lesson 3: Finding SA for Cylinder and Cone

This week, I have learned how to find the SA (Surface area) of a Cylinder and a Cone. It requires to remember formula and practice to put numbers in the formula. SA of Cylinder and Pyramid Before we start to calculate to find the SA, we need to learn the formula.  If you remember a wrong formula, not only you will end up having a wrong answer, but also wasting all calculations.  Let’s carefully go…

# Lesson 2: Multiplying and Dividing Power

This week, I have learned how to multiply and divide powers and how to solve negative exponent. It took time to understand but practicing many times lead me to get better. Multiply Powers When multiplying powers we must first learn some vocabularies, such as power, base, and exponent. The power is a number written in exponential form. Example: . This is a power. A base and the exponent consists in the power Example: . The 2 would be the base…
