This is a PPT based on mathematics around us...
hope it is useful to you...
and there are no unwanted slides( hopefully).

1. MATHEMATICS AROUND US

2. Maths in Commercial Usage Discount Banking Foreign Exchange Stock and Share Arithmetic ( Profit & Loss, Percentage, Ratio and Proportion, Time problem). Discount Transaction Statistics

3. How Algebra is Useful? Suppose we appoint a person for some workwe give him 2 options: Say : i . Rs 100/- per day ii.Rs 50/- per first day, then increase of Rs 5/-per the summing days. Which is better? 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

4. How the concept of Mean, Median & Mode are used in daily life? A shopkeeper keeps more stock of a particular type of shoe which has more sale. 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.

5. 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.

6. Geometry Study of shape, size, relative position of figures with properties of space. House building to find the floor area- this is needed for finding area of carpet or number of tiles. MECHANICS : It is concerned with the behaviour of physical bodies subject to forces or displacements. For example: Maximum distance a football can go when kicked by the goal keeper at an angle of 45°.

7. Maths In Biology & Medicine SYMMETRY is a general concept of studies in Science. Fish Sea Anemone Reconstruction of the shape of a tumor from CAT scans and other medical measurements. Protein modelling etc
