Properties of Addition and Multiplication

December 14, 2015 /




Sa exam, ito na siguro ang mga pinakamadaling klase ng tanong na lumalabas. Kaya nga lang, marami sa mga nag-eexam ang nakalimutan na ang mga ito. I won’t blame you if isa ka sa kanila. After all, it’s been years since you last had to memorize this.

In this video, I’ll teach you how I remember these properties easily. I’m not big on memorization pero I believe in information reconstruction. With the right mnemonics and memory aids, kaya rin ninyong sagutin kahit anong tanong about these properties pagdating ng exam.

Order of Operations Worksheet Set #1

October 23, 2015 /

Order of operations is one of the easiest types of questions na pwedeng lumabas sa exam. It’s also one of the easiest questions to get wrong. That’s because the discipline of following the correct order in solving the problems takes a lot of practice. You have to be so in tune with the rules of operations that they’re second nature to you.

So, ano ba ang tamang order?

  1. Parentheses
  2. Exponents
  3. Multiplication/Division
  4. Addition/Subtraction

If walang parentheses na nakalagay, place them yourself. That will help you prioritize the correct steps.

Here’s a set of five worksheets with increasing difficulty. Start with Worksheet #1 and move down.

Mean, Median, and Mode

October 13, 2015 /

There may be a couple of statistic questions in the examination. Kaya it’ll pay to brush up on these simple concepts-the mean, mode, median, and range.

So, how do you solve for them? Here’s how:

  • Mean = Average. All you have to do is to add all of the scores and divide it by the number of scores. For example: 3, 4, and 5 will give you a mean of 4 because (3+4+5) divided by 3 is 4.
  • Mode = The score with the most repetitions. In short, yung pinakasikat or uso. For example: 3, 4, 4, and 5 will have a mode of 4 because there are 2 4s and just one each of 3 and 5.
  • Median = Middle. Write all of the scores in ascending order and pick the number in the middle spot. For example: 3, 4, 5, will give you a median of 4 because it is the middle number.
  • Range = The largest score minus the smallest score. For example: 3, 4, and 5 will have a range of 2 because 5 – 3 is 2.

It’s time to put that into practice. Here are a couple of worksheets to get you started.

Mean, Median, Mode #1

Mean, Median, Mode #2

  1. Complementary Angles = 90 degrees
  2. Supplementary Angles = 180 degrees

Here are videos that will help you get a good grasp of this concept.

You can practice these concepts using the following worksheets:

Polynomials Worksheets #1

October 8, 2015 /

I know, I know, there’s no way that we can use this concept in real life. It’s not like we need to know how to factor special polynomials in order to buy stuff from the supermarket or calculate the amount of tax we need to pay. Yun nga lang, kasama pa rin ito sa Civil Service Exam.

Pero, if you don’t understand how to solve these problems, that doesn’t mean that you won’t pass the test. Usually, there’s just one or two questions about polynomials sa exam. As long as you have a solid grasp on the other topics, you’re good to go.

Adding and Subtracting Polynomials #1

Multiplying Monomials by Polynomials #1

Multiplying Special Binomials #1

Factoring Polynomials #1
