As a student who takes Additional Mathematics in SUMP, I am required to carry out a project work. This year the Curriculum Development Division, Ministry of Education has prepared two tasks for me.

I need to choose one project based on my interest. This project can be done in groups or individually but the students are required to submit an individually written report. Upon completion of the Additional Mathematics Project Work, we are able to gain valuable experiences and able to: Apply and adapt a variety of problem solving strategies to solve routine and non- routine problems; -Experience classroom environment which are challenging, interesting and meaningful and hence improve their thinking skills. Experience classroom environments where knowledge and skills are applied in meaningful ways in solving real-life problems -Experience classroom environments where expressing ones mathematical thinking reasoning and communication are highly encouraged and expected -Experience classroom environment that stimulates and enhances effective learning.

Acquire effective mathematical communication through oral and writing; and to use the language of mathematics to express mathematical ideas correctly and precisely -Enhance acquisition of mathematical knowledge and skills through problem-solving -Prepare ourselves for the demand of our future undertakings and in workplace -Realizes that mathematics is an important and powerful tool in solving real-life problems hence develop positive attitude towards mathematics. Train ourselves not only to be independent learners but also to collaborate, doctorate, and to share knowledge in an engaging and healthy environment Use technology especially the CIT appropriately and effectively -Train ourselves to appreciate the intrinsic values of mathematics and to become imperative and innovative -Realize the importance and the beauty of mathematics Part 1 Index numbers 1) An index number is a number that can be used to show changes in magnitude of a quantity over a specific period of time. ) The specific period over which the changes occurred is called the base time. The base usually equals to 100 and thus the index number is usually expressed as a percentage, but the % sign is not usually written. 3) The formula for calculating index of a quantity, I is: Index number, IQ x 100 CO where CO = quantity at base time, IQ = quantity at a specific time. 4) If the index number is 125, it indicates that there is a +25 points or 25% rise of the quantity from base time to the specific time. ) Conversely, if the index number is 97, it indicates that there is a -3 points or 3% fall of the quantity from base time to the specific time. U. S Consumer Price Index - Food and Beverage (it) Weight Weight is common word used in Asia. The meaning for weight is a weighting factor assigned to compensate for perceived advantage or a weight factor or ratio; eight. Weight can also be defined as the importance or value when compared with another thing An example for its usage is: "The admission holds 80% weight while the interview holds 20% weight of the admission process".

In a nutshell, weight can also be said as stake. Composite Index Composite index is a grouping of equities, indexes and other factors combined in a standardized way, providing a useful statistical measure of overall market or sector performance over time.

1. Unlike index number the index numbers and involves two or more quantities.
2. The weight is the alee or quantity assigned to each item. This terms provide the importance or significance of each quantity.
3. The formula of composite index is: Composite index, where = index number for item , = the corresponding weight for item

Composite index can also be defined as a group of indices combined to measure the overall price of an item over a period of time. For instance, we can take a look at the price of root canal in the year 2013 based on the year 2010. A composite index may also be used in the natural or social sciences to summarize complex or multidimensional data or redundant measures.

Usually, a composite index has a large number of factors which are averaged together to form a product representative of an overall market or sector. For example, the Nasdaq Composite index is a market capitalization-weighted grouping of approximately 5,000 stocks listed on the Nasdaq market. These indexes are useful tools for measuring and tracking price level changes to an entire stock market or sector. Therefore, they provide a useful benchmark against which to measure an investor's portfolio. The goal of a well-diversified portfolio is usually to outperform the main composite indexes (b) .

Ways of Weight Representations

1. Weight in a set of data can be represented in certain ways.
2. Pie
3. Percentage
4. Ratio part

2 1) Bar Chart We often hear complaints from the public about inflation. It causes an increase in the household expenditure in a family. So what is inflation and how does it affect us in our life? Basically, as citizens, we do get affected as it increases our household expenditure. With that, it will certainly cause problem to low-income families as their expenditure increase but at the same time, their monthly income remains the same.

But on the other hand, the capitalists will sure benefit from this situation as they are owners of these large corporations which conduct these businesses. The parties who will be least affected are the middle-class people and the super-rich citizens, I. E. The millionaires. Technically, inflation is caused by the price increase of certain items from time to time. In this part we're going to make a case study on my family household expenditure to investigate this so called "inflation"
