Week 7- Using quadratic formula

This week, I have learned how to use quadratic formula and see if there is a solution to the question. The equation .  Using -b+/- If there is a negative in the root sign, then the answer will not work. Example -3+/- -3+/- -3+/- Since there is -20 in the square root, it is not possible. However, if the answer was positive, there will have a answer to the equation. By…

Week 4- Adding Radical

This week, I have learned how to add radicals. At first, I thought it would be hard because adding fraction is harder than multiplying fraction. However, it was very easy. It has the same concept as fraction. Let’s try an example. +  For fraction, you leave the denominator and add the top, for radicals, you add the coefficient and leave the radicand alone. So it should look something like this…

Week 3- Absolute value

This week, I have learned how to solve and find the absolute value of each number. There are several rules to absolute value. Negative numbers that are inside the absolute value becomes positive number. You do the calculation before changing the negative number to positive number. It is like brackets, however, the difference between brackets and absolute values is that every number that comes out from an absolute values becomes…

Week 2 – Geometric Sequence

This week, I have learned how to solve a geometric sequence. The difference between geometric and arithmetic is that you have addition for arithmetic and multiplication on geometric. Vocabulary Geometric sequence : In geometric sequence, you use the formula, is the first term and r is the common ratio. To find the common ratio, you divide the second term from the first term. Example: r= r= r= 2 So, if…

Week 1 – My Arithmetic Sequence

Part 1 This week, I have learned how to solve arithmetic sequence and series. Before we begin, we must learn some vocabulary to be able to solve these questions. Arithmetic sequence: is a sequence of number that the difference between the consecutive terms is constant. Ex: The sequence 1 ,3, 5, 7, 9, …  is an arithmetic progression with common difference of 2. General term: To determine an expression for the…
