Mathematics and its importance
Mathematics is a fundamental part of human thought and logic, and integral to attempts at understanding the world and ourselves. Mathematics provides an effective way of building mental discipline and encourages logical reasoning and mental rigor. In addition, mathematical knowledge plays a crucial role in understanding the contents of other schoolsubjects such as science, social studies, and even music and art.
Firstly, we ask the question: why does mathematics hold such an important and unique place among othersubjects? That is, what is the significance of mathematics in the overall school curriculum? As a point of departure we offer a few thoughts on why mathematics should be treated as an important subject in overall curriculum.
 Mathematics has a transversal nature. If we reflect on the history of curriculum in general, then mathematics (geometry and algebra) were two of the seven liberal arts in Greek as well as in medieval times. This historical role supports the notion that mathematics has provided the mental discipline required for other disciplines.
 Mathematical literacy is a crucial attribute of individuals living more effective lives as constructive, concerned and reflective citizens. Mathematical literacy is taken to include basic...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to eachother; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between nonmoving surfaces, and kinetic friction between moving surfaces; lubricated friction which is a case of fluid friction where a fluid separates two solid surfaces; skin friction which is a component of drag, the force resisting the motion of a fluid across the surface of a body; internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation and sliding friction.
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence...
...This led to a growing sense of alienation among the low caste.
Communist groups like CPIML, MCC, and People's War took advantage of this and instigated the low caste people to take up arms against establishment, which was seen as a tool in the hands of rich. They started taking up lands of the rich by force, killing the high caste people. The high caste people resorted to use of force by forming their own army, Ranvir Sena, to take on the naxalites. The State witnessed a bloody period in which the groups tried to prove their supremacy through mass killings. The police remained a mute witness to these killings, as they lacked the means to take any action.
The Ranvir Sena has now significantly weakened with the arrest of its top brass. The other groups are still active.
There have been arrests in various parts of the country, particularly those made by the Delhi and Mumbai police in the recent past, indicating that extremist/terrorist outfits have been spreading their networks in this state. There is a strong suspicion that Bihar is also being used as a transit point by the smallarms, fake currency and drug dealers entering from Nepal and terrorists reportedly infiltrating through Nepal and Bangladesh.
In recent years, these attacks by various caste groups have come down with better government being practised.

...Does Maths Help You with OtherSubjects?
Maths helps you with othersubjects because it enables the student to be a logical thinker and have skills in statistical analysis. Maths also gives skills which are closer to those used in the workplace as opposed to skills learned in othersubjects. Realistically speaking, numbers, problem solving and equations are actually used more in both home and working life than you may have originally thought.
How Is Mathematics Used in OtherSubjects?
The exasperated sighs of students who insist that they'll never need the information they learn in math classes are so common that many teachers and parents have stock answers for the ways math functions in everyday life. But math is also relevant to a wide variety of academic subjects, which means that a student who does poorly in math could end up struggling in othersubjects.
Science
Science and math are intimately connected, particularly in fields such as chemistry, astronomy and physics. Students who can't master basic arithmetic skills will struggle to read scientific charts and graphs. More complex math, such as geometry, algebra and calculus, can help students solve chemistry problems, understand...
...Math and Science
The math teacher can teach students about exponential notation. Once students become proficient in reading and writing numbers in exponential form, and in converting numbers between exponential, factor, and standard form, they can apply this knowledge to topics in science. For example, they can write the distance between the sun and each planet using scientific notation. For advanced students, you can teach them about negative exponents. Then they can explore the halflife of certain radioactive elements, or the size of bacteria and viruses.
Explore many scientific facts, such as the boiling and freezing point of liquids, the melting and freezing points of solids, and the temperature of planets,
Have you been to the playground lately? You'll find many connections between algebra, science, and the real world in our article entitled

Math and Social Studiesstudents apply these skills to topics in Social Studies. For example, they can draw bar graphs to compare the Population, Per Capita Income, and Population Density of various countries. For other connections between math and social studies

...valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the offeree before it is being accepted. In addition, the acceptance has to be unqualified, unconditional and made by a positive act. In the case of Beauty and Stylish, a positive act refers to the signing of the contract. All terms of the offer must be accepted without any changes and cannot be subjected to any condition, taking effect only upon fulfillment of that condition. When Beauty and Stylish enter into the agreement, they must intend to bind and bound legally to each other by their agreement. This is the intention to create legal relations between two parties. In the meanwhile, this contract must possess consideration. A contract must therefore be a twosided affair, with each side providing or promising to provide something of value in exchange for what the other is to provide.
Every contract, whether oral or written, contain terms. The terms of a contract set out the rights and duties of the parties. Terms are the promises and undertakings given by each party to the other. They form the substance of a contract and they specify...

Solution:
[pic]
There are 24 ways to test three out of your four friends if order matters.
Try this problem:
How many different ways can a city building inspector visit five out of six buildings in the city if she visits them in a specific order?
Combination  A combination is a counting situation in which order is not important.
If order does not matter, then AB is the same as BA.
Example 3:
The art club has 4 members. They want to choose a group of three to compete in a regional competition. How many ways can three members be chosen?
Because the members of the group do not have specific jobs, order does not matter. In other words, choosing Taylor, Aubrey, and Justin in the same as choosing Aubrey, Taylor, and Justin. Therefore, we need to use the combination formula to solve this problem.
