Algebra (from Arabic "al-jabr" meaning "reunion of broken parts") is one of the broad parts of mathematics, together with number theory, geometry and analysis.

In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

As such, it includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra.

Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics.

Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Calculus (from Latin calculus, literally "small pebble used for counting") is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.

It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus.

Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.

Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Gottfried Leibniz.

Today, calculus has widespread uses in science, engineering and economics.

In mathematics education, precalculus is a course with university or high school level algebra and trigonometry that is designed to prepare students for the study of calculus.

Schools often distinguish between algebra and trigonometry as two separate parts of the coursework.

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet.

A LAN messenger operates in a similar way over a local area network.

Short messages are typically transmitted bi-directionally between two parties, when each user chooses to complete a thought and select "send".

Some IM applications can use push technology to provide real-time text, which transmits messages character by character, as they are composed.

More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat.

An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages.

They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived.

Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.
