Simple equations in mathematics are mathematical statements that use variables, numbers, and mathematical operations like addition, subtraction, multiplication, and division to assert the equality between two expressions.
More detailed answer question
Simple equations in mathematics are the foundation upon which more complex mathematical concepts are built. Essentially, they are mathematical statements that assert the equality between two expressions using variables, numbers and mathematical operations such as addition, subtraction, multiplication and division.
As Stanford Mathematics Professor Keith Devlin puts it: “Equations are useful to model real-world scenarios and to test the accuracy of such models. They also provide a powerful tool for solving practical problems in physics, engineering, economics, computer science, and many other fields.”
Here are some interesting facts about simple equations:
- The concept of equations dates back thousands of years to ancient Babylon, where clay tablets containing mathematical calculations have been found with examples of equations.
- The equal sign (=) we use to represent the equality in an equation was invented by Welsh mathematician Robert Recorde in 1557.
- Equations are not always easy to solve, and in some cases, their solutions are unknown. These unresolved equations are known as “unsolved problems” and include famous examples such as Fermat’s Last Theorem and the Riemann Hypothesis.
- Mathematicians use simple equations in algebraic manipulations to solve more complex problems. The manipulation of equations is known as “algebraic reasoning” and has practical applications in fields such as engineering, physics, and economics.
- An example of a simple equation is 2x + 1 = 5, where x is the variable and the equation asserts that the value of x that satisfies the equation is 2.
Here’s a table of some common mathematical operations used in simple equations:
Operation | Symbol | Example
Addition | + | 2 + 2 = 4
Subtraction | – | 5 – 3 = 2
Multiplication | * | 3 * 4 = 12
Division | / | 12 / 4 = 3
In summary, simple equations may seem basic, but they are essential in mathematics and have practical applications in many fields. As American mathematician John Tukey said, “The best thing about being a statistician is you get to play in everyone’s backyard.”
Video response
The Math Antics video explains how to solve simple equations in Algebra by rearranging the equation so that the unknown value is on one side of the equal sign. By doing the opposite operation (subtraction for addition and addition for subtraction) on both sides of the equation, students can isolate the unknown and find its value. The video covers addition, subtraction, and taking away an unknown from a number, emphasizing that the same process applies to decimals, fractions, and any symbol used as the unknown. The video encourages viewers to practice solving equations on their own.

A simple equation refers to a mathematical equation that expresses the relationship between two expressions on both sides of the ‘equal to sign. This category of an equation consists of a variable, usually in the form of x or y. Solving simple equations often requires rearranging it.
The basic Maths formulas include arithmetic operations, where we learn to add, subtract, multiply and divide. Also, algebraic identities help to solve equations. Some of the formulas are: (a + b) 2 = a 2 + b 2 + 2ab (a – b) 2 = a 2 + b 2 – 2ab a 2 – b 2 = (a + b) (a – b)
What is Simple Equation? A mathematical equation which represents the relationship of two expressions on either side of the sign. It mostly has one variable and equal to symbol. Example: 2x – 4 = 2. In the given example, x is a variable. Before understanding this, let us see an example, to visualize and interpret the meaning of simple equations.

In this way, What is an example of a simple equation in math? For example, the equation 3 x 4 = 12 contains single terms that the operation and equal signs separate. Another example of a simple equation is 5 + 11 – 2 = 14, where you see multiple terms that split between two operation signs and the equal sign.
Considering this, What is the difference between equation and simple equation?
Answer to this: Remember this! A linear equation in one variable is an equation that can be written in the form a x + b = 0 , where a , b ∈ Q and. A linear equation that has only one variable is a simple equation.
What is the rule for simple equations?
If we add or subtract the same number on both sides of the equation, the value remains the same. Similarly, if we multiply or divide the equation with the same number on both sides, the equation remains the same.

Additionally, How do you solve an equation? As an answer to this: Solving an equation is the process of getting what you’re looking for, or solving for, on one side of the equals sign and everything else on the other side. You’re really sorting information. If you’re solving for x, you must get x on one side by itself. Some equations involve only addition and/or subtraction. Solve for x.
