8. 8. For ex. i. 30 x 100 = 3000 P.M ii. 50 + d = S30 = 30 2 x 50 + (30 -1) 5 2 = 15 [ 100 + 29 x 5] = 15 x 245 = 3675
9. 9. Statistics • Collection • Analysis • Interpretation or Explanation • Presentation of Data • Prediction • Forecasting
10. 10.  Geographical interpretation  Quality  Engineering statistics  Analysis of data from chemistry  Sports (Cricket/Baseball)  Statistical survey  Business statistics

Here the concept of MODE applies.  The average daily expenditure in a month of a family gives the concept of MEAN.  If 15 people of different heights are standing height-wise, then the middle man’s height is the MEDIAN height.
12. 12. Calculus  It is the study of change  It includes limits, derivatives, integrals and infinite series.  It helps us to find the area of figures, to know the acceleration of a car moving in a highway with a uniform speed. Also, the movement of an artificial satellite, ship etc.
13. 13. Number Theory It is the branch of pure Maths concerned with properties of numbers. It is used for creating codes for ATM/ Credit Cards.
