### Termonologies used in mathematics by Sajjad Ahmad Awan TE DTSC Khushab

1. 1. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 1
3. 3. Education: Education means the change in behaviour and attitude. 2. Mathematics: It is the branch of science which deals with calculations known as mother of science. Its branches are Mathematic, Algebra and Geometry. 1. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 3
4. 4. Terminology: A specific word that is used for a specific thing is known as terminology. 3. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 4
5. 5. 1. Specific Objectives: To make the student familiar with the definitions of mathematical terms.  To inculcate the concept of these terms.  To make the students understand these terms completely and make them able to use these terms in mathematical applications.  3/4/2014 5
6. 6. 2. General Objectives: To enhance the mathematical understanding of the students.  To enhance the mathematical skills of the students.  To provide the students mathematical practice regarding these terms.  Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 3/4/2014 6
7. 7.  Symbol: Generally a symbol refers to some image or objects which suggests to some thing else. For example: Basic Symbols used in Mathematics: = These two parallel lines are named as symbol equal to. ≠ This named as not equal to. - This symbol is named as Subtract. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 7
8. 8. X It is a multiplication sign. < This sign named as greater than. >This sign named as less than. Є This is named as the member of. U This symbol shows the union of two sets. ∩ This symbol shows the intersection of two sets. ( ) This sign is known parenthesis. @ It is taken “At the Rate of”. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 8
9. 9.  Set: A set is collection of well defined objects  Sub Set: If A and B are two sets and every member of set A is the member of set B, then set A is as sub set of set B.  Union of two Sets: The union of two sets A and B is set consisting of all the elements which are in set A or in set B. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 9
10. 10.  Intersection of Two Set: The intersection of two sets A and B is a set consisting of all the common elements of sets A and B.  Power Set: If A is any set then the set consisting of all the subsets of the set A is called power of A.  Null Set: If there is no element present in a set it is called a null set. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 10
11. 11.  Ratio: A relation between two quantities in same units i.e. a:b  Proportion:A relation between two ratios is called proportion. i.e. a:b:: c:d  Direct Proportion: If a proportion between two ratios is such that with the increase one ratio the second ratio may rise is called direct proportion. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 11
12. 12.  Inverse Proportion: If a proportion between two ratio is such that with the rise of one ratio the second decreased that is called inverse proportion.  Percentage: Percentage is such common fraction, in which denominator consists 100 i.e. 12% means 12/100. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 12
13. 13.  Profit: The sale price of product is more than the purchase price is called profit. i.e Net Profit = Sale Price-Purchase Price.  Loss: The purchase price is more than the sale price is called loss. i.e. Loss = Purchase Price – Sale Price  Profit Loss Percent: The Profit or loss on product purchased in 100 R.s is called profit percent. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 13
14. 14.  Algebra: It is the branch of mathematics which deals generalized arithmetic to solve the complicated problems.  Constant: The value which remains fixed and does not change is called constant. e.g: 2,3,5,8.  Variable: The value which is not fixed and varies is called variable. e.g: X,Y,Z. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 14
15. 15.  Co-efficient: The number which is multiply by variable is called co-efficient. e.g: 3x,5y,etc.  Equation: An open sentence which shows “=“ among two expressions is called equation. e.g: 3x=12, x+2=9.  In-equation: Such sentences in which symbols < or > used are called in-equation. e.g: 3x>12, x<7. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 15
16. 16.  Geometry: Geometry means the measurement of earth.  Square: The shape having four equal sign with four right angles is called square.□  Rectangle: The shape which consists of four sides having opposite sides equal is called rectangle. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 16
17. 17.  Sphere: A sphere is solid bounded by a single curve surface with equal distance for all sides.©  Centre: The fixed point of sphere is called a centre.  Radius: The distance from centre of circle upto the outer side.  Angle: The two rays with common end point is called angle. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 17
18. 18.  The students will understands all these terminologies very well.  The students will be able to improve their knowledge.  The well qualified students will take active part in the progress of Pakistan. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 18
19. 19.  The post graduate teachers should be provided in primary school of rural areas of Punjab.  AV aids should be provided in school of remote areas for the better quality of education.  Teachers training courses should be conducted after 3 years for newly recruited and senior teachers. 3/4/2014 Sajjad Ahmad Awan PhD Research Scholar TE DTSC Khushab 19
