Pre Algebra

Pre-algebra is a primary branch of algebra designed to prepare students for a standard high school algebraic course. Students are introduced to integers, fractions, square roots, step equations, linear equations, and decimals and are taught how to solve basic equations using variables. Taking a pre-algebra course can give students initial exposure to the fundamentals of algebra and help them perform better in future courses.

Pre-algebra is a branch of mathematics that deals with the topics to be covered before algebra 1, and algebra 2 to develop the basic understanding in students. The topics in pre-algebra consist of factors and multiples, patterns, ratios, percentages, exponents intro, order of operations, variables & expressions, linear equations. Let us discuss these listed topics in detail in our next section

Pre-algebra is divided into multiple sub-topics. There are seven-plus chapters in this branch and each chapter is divided into several sub-topics.

Number Theory

• Whole Numbers
• Roman Numerals
• Integers
• Rational Numbers
• Real Numbers
• Pythagorean Theorem
• Absolute Value

Factors and Multiples

• Factors
• Multiples
• Prime numbers and Composite numbers
• Prime factorization

Linear Equations

• Algebraic Expressions
• Solving Linear Systems by Substitution
• System of Equations Solver
• Solutions of a Linear Equation
• Variable expressions
• Linear Equations

Ratio and Proportion

• Ratio
• Proportion

Exponents and Square Root

• Fractions
• Exponents
• Order of Operations
• Square root

Statistics

• Mean, Median, Mode
• Probability

Here are a few formulas related to pre-algebra which you may feel are handy to have.

• Speed = Distance/Time
• Pythagoras Theorem: c² = a² + b², where 'c' is the hypotenuse and 'a' and 'b' are two legs of a right triangle.
• Profit = Selling price - Cost price
• Loss = Cost price - Selling price
• Profit percentage = profit/cost price × 100
• Loss percentage = loss/cost price × 100
• Discount = List Price - Selling Price and Discount (%) = (Discount/List Price) × 100
• Slope of a line joining the points (x₁, y₁) and (x₂, y₂) is m = (y₂ - y₁) / (x₂ - x₁)
• The point slope formula of a line is y - y₁ = m (x - x₁)
• Distance between two points (x₁, y₁) and (x₂, y₂) is d = √[(x₂ – x₁)² + (y₂ – y₁)²]

Pre-algebra and algebra can be distinguished based on the complexity of the topics covered under both branches separately. The following table explains the important differences between pre-algebra and algebra.

Pre-Algebra worksheets are extremely helpful for students to prepare for higher grade algebra. Below mentioned are few readily downloadable resources for your practice.

Why is Pre-Algebra Important?

Pre-algebra provides students an opportunity to learn the basics to understand the complexity of algebra. It develops a basic understanding of variables, equations, and exponents along with the knowledge of how to use the order of operations with algebraic expressions.

How Do You Start Pre-Algebra for Beginners?

Pre-algebra is a building block of mathematics. If you are a beginner you can definitely follow the below-listed points while practicing pre-algebra. These points are:

• One must aware of arithmetic operations.
• Remember PEMDAS or BODMAS.
• Must know how to solve negative numbers.
• Learn the difference between variables, exponents, equations, and coefficients.
• Solve more practice questions.

Is Pre-Algebra Harder than Algebra?

As a name described Pre-algebra is a primary branch of algebra where all the basic concepts are covered to understand the further complex topics of algebra. It is not at all difficult if learned with the best-sophisticated approach.

What do You Learn in Pre-Algebra?

In pre-algebra, we learn about the following listed topics.

• Factors
• Multiples
• Prime numbers and Composite numbers
• Prime factorization
• Linear Equations
• Variables, coefficient, degree
• Ratio and Proportion
• Exponents
• Fractions
• Order of Operations

What Comes After Pre-Algebra?

After pre-algebra, the next subject is algebra 1, algebra 2. These have advanced concepts that require a pre-requisite understanding of the concepts covered in pre-algebra.

What is the First Thing you Learn in Pre-Algebra?

The first thing students learn in algebra 1 is real numbers and their operations. The basic concepts covered under pre-algebra form the basis of the advanced algebraic concepts.

What is Standard Form in Pre-Algebra?

A standard form in pre-algebra is a form of writing a given mathematical concept like an equation, number, or an expression in a form that follows certain rules.
