Areas Of Mathematics With The Word Algebra In Their Name

Some subareas of algebra have the word algebra in their name linear algebra is one example. Others do not: group theory, ring theory, and field theory are examples. In this section, we list some areas of mathematics with the word “algebra” in the name.

  • Elementary algebra, the part of algebra that is usually taught in elementary courses of mathematics.


Elementary algebra is the most basic form of algebra. It is taught to students who are presumed to have no knowledge of mathematics beyond the basic principles of arithmetic. In arithmetic, only numbers and their arithmetical operations occur. In algebra, numbers are often represented by symbols called variables . This is useful because:

  • It allows the general formulation of arithmetical laws , and thus is the first step to a systematic exploration of the properties of the real number system.
  • It allows the reference to “unknown” numbers, the formulation of equations and the study of how to solve these.
  • It allows the formulation of functional relationships. = 3x 10, where f is the function, and x is the number to which the function is applied”.)

Linear Equations In Standard Form

The standard form or the general form of linear equations in one variable is written as, Ax + B = 0 where A and B are real numbers, and x is the single variable. The standard form of linear equations in two variables is expressed as, Ax + By = C where A, B and C are any real numbers, and x and y are the variables.

All quantities of the ingredients and the number of servings make the variables. The cook uses Algebraic intelligence to ensure that not only the food is available in sufficient quantity, but also it is tasting great. Such is the extent of Algebra use in cooking!

What Is A Linear Equation

Algebra 1 Concepts Fri Oct 21

An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.

Linear Equation Definition: A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a ‘linear equation’.

There are linear equations in one variable and linear equations in two variables. Let us learn how to identify linear equations and non-linear equations with the help of the following examples.

Non-Linear, the power of the variable x is 2
y + x = 6 Non-Linear, the power of the variable y is 1/2
y + 3x – 1 = 0
Non-Linear, the power of the variable x is 2

How Are Algebra And Geometry Different

Algebra is a branch of mathematics in which arithmetic operations and other formal manipulations are applied to abstract symbols rather than specific numbers. Geometry is the branch of mathematics that deals with the shape of objects, their spatial relations, and the properties of the space the objects are in.

algebra, branch of mathematics in which arithmetical operations and formal manipulations are applied to abstract symbols rather than specific numbers. The notion that there exists such a distinct subdiscipline of mathematics, as well as the term algebra to denote it, resulted from a slow historical development. This article presents that history, tracing the evolution over time of the concept of the equation, number systems, symbols for conveying and manipulating mathematical statements, and the modern abstract structural view of algebra. For information on specific branches of algebra, seeelementary algebra, linear algebra, and modern algebra.

How Is Algebra Used In Business

Algebra can be used to predict sales and how much a customer will spend. Algebra is used to estimate the life time value of a customer, which calculates the percentage of annual spend.

The formula used is:

y = 12 + 8x

Algebra is used because x can change. y represents the percentage that a customer will spend in a year.

Imagine that a customer spends £50 in their first 2 months with us. We have to include their first month as x = 0, so their 2nd month will be x = 1.

Now we know x = 1, we can substitute it into y = 12 + 8x.


y = 12 + y = 20%

If 20% = £50. Then over a full year, 100% will equal £250 . This means we can predict a customer will spend £250 a year.

What Is A Linear Equation Explain With An Example

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line. This is the reason why it is termed as a ‘linear equation’. There are linear equations in one variable, in two variables, in three variables, and so on. The standard form of a linear equation in one variable is of the form Ax + B = 0. An equation of the form Ax + By = C is called a linear equation in two variables. A few examples of linear equations are 5x + 6 = 1, 42x + 32y = 60, 7x = 84, etc.

How To Simplify Algebraic Expressions

To simplify an algebraic expression, we just combine the like terms. Hence, the like variables will be combined together. Now, out of the like variables, the same powers will be combined together. For example, let us take an algebraic expression and try to reduce it to its lowest form in order to understand the concept better. Let our expression be:

x3 + 3×2 2×3 + 2x x2 + 3 x

= + + + 3

= x3 + 2×2 + x + 3

Hence, the algebraic expression x3 + 3×2 2×3 + 2x x2 + 3 x simplifies to x3 + 2×2 + x + 3.

Making A Schedule Of Activities

Pin by Jessica Anson on Books Worth Reading

When you are making a schedule of activities, you actually are dividing the whole day and summing up the times taken to complete the intended activities. So, the simple process of finding whether you will reach the office on time or not if you have chosen to set the alarm at 6 am, is an algebraic calculation that you do mentally. Hours, times taken in various activities, and some new unforeseen tasks are Algebraic variables in real life, that you have to work upon to be on time at the office or any meeting.

Scheduling is common to all. And, Algebra knowledge makes you the true master of your day because of which you know how to use variables and put them in an equation. Thus, you get all things done right and on time due to Algebra playing its role.

Doing Interiors And Landscape Designing

Not only interiors planning or landscape designing, in fact, but the whole of Architecture stream employs Algebra. When the designers are trying to find the correct elevation or try to arrive upon the collection of things required to do a space, they make use of data like measurements of the space and that of the items to fit in.

This is the Algebra use in real life that helps to understand how things are going to amplify the looks of the space and will contribute to the overall appearance of the space.

Similarly, in an office environment, the decisions like moving to larger spaces to accommodate people or designing cabins are some of the premises where Algebraic calculations come into play.

Types Of Algebraic Expressions

The types of algebraic expressions are based on the variables found in that particular expression, the number of the terms of that expression, and the values of the exponents of the variables in each expression. Given below is a table that divides the algebraic expressions into five different categories. Let us have a look at the table.

A Kid Developing Spatial Intelligence

When kids have just started to learn to walk or stand, they need to find the safe height or distance of any object that they can choose to rely upon for standing or walking. Even while using a walker, they are actually using Algebra mentally to find how far the walker will take them before hitting any object, by propelling it at a particular speed. Similarly, Algebra comes into action when the kid is trying to find whether the shape of an object is wieldable or not.

Also, Algebra is there in action when the kids are trying to play spatial reasoning games. They visualize the shapes and patterns and solve puzzles only because of certain Algebraic equations that they may come to know about in later stages of their education. So, though without cognition, kids gather spatial intelligence by applying Algebra.

Linear Equations In One Variable

SAT Math: Critical Concepts for an 800 – Heart of Algebra (Part 1 of 4)

A linear equation in one variable is an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution. It is the easiest way to represent a mathematical statement. This equation has a degree that is always equal to 1. A linear equation in one variable can be solved very easily. The variables are separated and brought to one side of the equation and the constants are combined and brought to the other side of the equation, to get the value of the unknown variable.

Example: Solve the linear equation in one variable: 3x + 6 = 18.

In order to solve the given equation, we bring the numbers on the right-hand side of the equation and we keep the variable on the left-hand side. This means, 3x = 18 – 6. Then, as we solve for x, we get, 3x = 12. Finally, the value of x = 12/3 = 4.

Problem Solving In Egypt And Babylon

The earliest extant mathematical text from Egypt is the Rhind papyrus . It and other texts attest to the ability of the ancient Egyptians to solve linear equations in one unknown. A linear equation is a first-degree equation, or one in which all the variables are only to the first power. Evidence from about 300 bc indicates that the Egyptians also knew how to solve problems involving a system of two equations in two unknown quantities, including quadratic equations. For example, given that the perimeter of a rectangular plot of land is 100 units and its area is 600 square units, the ancient Egyptians could solve for the fields length l and width w. However, throughout this period there was no use of symbolsproblems were stated and solved verbally. The following problem is typical:

  • Method of calculating a quantity,
  • multiplied by 1 1/2 added 4 it has come to 10.
  • What is the quantity that says it?
  • First you calculate the difference of this 10 to this 4. Then 6 results.
  • Then you divide 1 by 1 1/2. Then 2/3 results.
  • Then you calculate 2/3 of this 6. Then 4 results.
  • Behold, it is 4, the quantity that said it.
  • What has been found by you is correct.

Note that except for 2/3, for which a special symbol existed, the Egyptians expressed all fractional quantities using only unit fractions, that is, fractions bearing the numerator 1. For example, 3/4 would be written as 1/2 + 1/4.
