![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](https://image.slidesharecdn.com/maths-170205084846/85/MATHEMATICS-AROUND-US-3-320.jpg)

- 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
