A police station has 25 vehicles consisting of motorcycles and cars. The total number of tyres of both motorcycles and cars equal to 70. Find the number of motorcycles and cars the station has.
 
Answer
 
First strategy : Draw a Diagram
 
Step 1: Understanding the problem
 
Given : 25 vehicle (motorcycles and cars)
 
  Total num of tyres = 70
 
Find : Num of motorcycles
 
  Num of cars
 
Step 2: Develop a plan
 
How should we approach this problem? We can make a diagram.
 
First, we must draw 25 vehicles with two tyres. Then, we must add the remaining tyres to the vehicle until the number of tyres equal to 70. After that, we can see how much motorcycles and cars.
 
Step 3: Implement the plan
 
Before we add 2 more tyres to make the number of tyres become 70:
 
OO OO OO OO OO
 
OO OO OO OO OO
 
OO OO OO OO OO
 
OO OO OO OO OO
 
OO OO OO OO OO
 
Total number of tyres before adding the remaining tyres are 50
 
The remaining tyres are 20
 
After we add 2 more tyres to make the number of tyres become 70:
 
OOOO OOOO OOOO OOOO OOOO
 
OOOO OOOO OOOO OOOO OOOO
 
OO OO OO OO OO
 
OO OO OO OO OO
 
OO OO OO OO OO
 
 
Sign: OOOO – Car OO - Motorcycle
 
 
From this sketches, we can see how much number of motorcycles and cars at the police station. There are 15 motorcycles and 10 cars in the police station.
 
 
Step 4: Looking Back
 
Did we answer the correct question, and does our answer seem reasonable? Yes. (If you want to know our answer is correct or not, you must count the number of vehicle’s tyres).
 
 
 
Second strategy : Use a table
 
Step 1: Understanding the problem
 
What is the question we have to answer? How many motorcycles and cars in the police station.
 
How many vehicles in the police station? 25 vehicles.
 
How many number of vehicle’s tyres in police station? 70 tyres.
 
How many tyres that motorcycles have? 2 tyres.
 
How many tyres that cars have? 4 tyres.
 
 
Step 2: Develop a plan
 
What strategy will help here? We could model this on paper, but accuracy would suffer. We could also use equations. But, let’s make a table.
 
 
Step 3: Implement the plan
 
Firstly, we make a table with 5 rows and 3 columns. Then, we choose our target. For example, in the police station have 6 cars and 19 motorcycles. So we can see the total of vehicles in the police station is 62 vehicles. Then, we try and error with the same ratio until we get the answer which are 15 motorcycles and 10 cars:
 
CARS
 
( 4 TYRES) MOTORCYCLES
 
(2 TYRES) TOTAL OF VEHICLES (70 TYRES)
 
6 19 62
 
7 18 64
 
8 17 66
 
9 16 68
 
10 15 70
 
 
Calculation:
 
1 car have 4 tyres. 1 motorcycles have 2 tyres.
 
So, if there has 6 cars and 19 motorcycles...
 
6 x 4 = 24 and 19 x 2 = 38
 
And the total of vehicles are 62 (24+38). But, the answer is wrong.
 
 
So, we try and error with the same ratio until we get the correct answer which are 10 cars and 15 motocycles:
 
10 x 4 = 40 and 15 x 2 = 30. The total of vehicles are 70 (40 + 30). The answer is correct.
 
 
Step 4: Looking back
 
Did we answer the question asked? Yes.
 
Does our answer seem reasonable? Yes.
 
 
ONE STRATEGY THAT IS DEEMED TO BE MOST EFFICIENT AND JUSTIFY
 
After studied these two strategies, this problem can be overcome by using a diagram. This strategy is more efficient because it is easier to solve this kind of problem. In addition, by using table, we have to list the information and do a lot of calculation. But, by using a diagram, we can easily see the situation and understand the problem.

Mathematics is the science of structure and change. Mathematics is important to the other sciences because it provides rigourous methods for developing models of complex phenomena. Such phenomena include the spread of computer viruses on a network, the growth of tumors, the risk associated with certain contracts traded on the stock market, and the formation of turbulence around an aircraft. Mathematics provides a kind of "quality control" for the development of trustworthy theories and equations which are important to people in most modern technical discplines such as engineering and economics.

Modern mathematics is built around a system of axioms, which is a name given to "the rules of the game." Mathematicians then use various methods of formal proof to extend the axioms to come up with surprising and elegant results. Such methods include proof by induction, and proof by contradiction, for example.


Mathematical Subject Classification

There are numerous categories and subcategories of mathematics, as shown by the American Mathematical Society's Mathematics Subject Classification scheme.

A common way of classifying mathematics is into Pure Maths and Applied Maths. Pure Maths is maths which is studied in order to make mathematics more stable and powerful, and knowledge of Pure Maths is required to understand the foundations of Applied Maths. Pure Maths is often considered to be divided into the areas of Higher Algebra, Analysis, and Topology.

Applied Maths consists of taking the techniques from Pure Maths and using them to develop models of "the real world." Applied Maths is sometimes considered to be divided into the areas of Dynamical Systems, Approximation Techniques, and Probability & Statistics. There are also various Applied Mathematical disciplines which use a combination of these areas but focus on a particular type of application. Examples include Mathematical Physics and Mathematical Biology.

Arithmetic

Main article: Arithmetic

Arithmetic is a branch of mathematics and their basic properties under the operations of addition, subtraction, multiplication and division and exponentsas well as percents radicals fractions and decimals

In general, more basic properties of the integers belong to arithmetic while deeper or more difficult results belong to number theory, but the boundary is not extremely clear. For instance, modular arithmetic might be considered part of arithmetic as well as part of number theory.

One of the earlier arithmetic devices was the abacus.

according to Wikipedia Arithmetic comes from the Greek word arithmos, "number" and tiké [téchne], "art")

Algebra

In mathematics, algebra can denote many things. As a subject, it generally denotes the study of calculations on some set. In high school, this can the study of examining, manipulating, and solving equations, inequalities, and other mathematical expressions. Algebra revolves around the concept of the variable, an unknown quantity given a name and usually denoted by a letter or symbol. Many contest problems test one's fluency with algebraic manipulation. Algebra can be used to solve different types of equations, but algebra is also many other things Modern algebra (or "higher", or "abstract" algebra) deals (in part) with generalisations of the normal operations seen arithmetic and high school algebra. Groups, rings, fields, modules, and vector spaces are common objects of study in higher algebra. Algebra Involving Equation Algebra can be used to solve equations as simple as $3x=9$ but in some cases so complex that mathematicians have not figured how to solve the particular equation yet. As if to add to the confusion, "algebra" is the name for a certain kind of structure in modern algebra.

Modern algebra also arguably contains the field of number theory, which has important applications in computer science.
