At the airport

Before the flight passengers are requested to arrive at the airport 2 hours before departure time. They must register their tickets, get a seat assignment, and weigh and check their luggage. Most airlines have at least 2 classes of travel, first class and economy class. Economy class tickets are much less expensive. Generally this weight limit is 20 kg of checked baggage for economy class passengers and 30 kg for first class passengers. Every passenger is also allowed one small carry-on bag, for instance a laptop computer or small suitcase.

The rules for passengers who are travelling abroad are similar in most countries but there are, sometimes, slight differences. Here are some things to remember: if, for instance, you need to go through Customs, try to fill in the customs declaration before you talk to the customs officer. He will ask every passenger the same, routine questions about whether he is carrying anything he wants to declare: like tobacco, alcohol, presents, and sums of money. At the check-in counter, your ticket is looked at, your things are weighed and labelled with their destination. The next formality is filling in the immigration form and going through passport control. Remember to have a black or blue pen with you because the immigration form has to be filled in block letters. You write your name, nationality, permanent address and the purpose of your trip. In most countries there is also a security check when your carry-on-luggage is inspected. After fulfilling all these formalities you go to the departure lounge where you can have a snack, read a paper or buy something in the duty-free shop and wait for the announcement to board the plane.

When you arrive at your destination, some of these formalities will be repeated. At the airport you may be met by a specially trained dog whose job is to make sure that no passengers are carrying any illegal drugs. In addition, the immigration officer might want to inspect your visa, your invitation and even your return ticket.

Arithmetic operations

The traditional arithmetic operations are addition, subtraction, multiplication and division, although more advanced operations (such as manipulations of percentages, square root, exponentiation, and logarithmic functions) are also sometimes included in this subject. Arithmetic is performed according to an order of operations. Any set of objects upon which all four operations of arithmetic can be performed (except division by zero), and wherein these four operations obey the usual laws, is called a field.

Addition (+)

Addition is the basic operation of arithmetic. In its simplest form, addition combines two numbers, the addends or terms, into a single number, the sum.

Adding more than two numbers can be viewed as repeated addition; this procedure is known as summation and includes ways to add infinitely many numbers in an infinite series; repeated addition of the number one is the most basic form of counting.

Addition is commutative and associative so the order in which the terms are added does not matter. The identity element of addition (the additive identity) is 0, that is, adding zero to any number will yield that same number. Also, the inverse element of addition (the additive inverse) is the opposite of any number, that is, adding the opposite of any number to the number itself will yield the additive identity, 0. For example, the opposite of 7 is (-7), so 7 + (-7) = 0.
