Basic Mathematics Rules For Beginners
Here are some basic mathematical rules that are essential for beginners:
 Addition:
 Commutative Property: Changing the order of the numbers does not affect the result. For example, a + b = b + a.
 Associative Property: Changing the grouping of the numbers does not affect the result. For example, (a + b) + c = a + (b + c).
 Identity Property: Adding a zero to a number does not change its value. For example, a + 0 = a.
 Subtraction:
 Subtraction is the inverse operation of addition. If a – b = c, then a + c = b.
 Multiplication:
 Commutative Property: Changing the order of the numbers does not affect the result. For example, a × b = b × a.
 Associative Property: Changing the grouping of the numbers does not affect the result. For example, (a × b) × c = a × (b × c).
 Identity Property: Multiplying a number by one does not change its value. For example, a × 1 = a.
 Zero Property: Multiplying any number by zero gives zero. For example, a × 0 = 0.
 Division:
 The division is the inverse operation of multiplication. If a ÷ b = c, then a = b × c.
 Division by zero is undefined and not possible.

Order of Operations (PEMDAS/BODMAS):
 Parentheses/Brackets: Perform operations within parentheses or brackets first.
 Exponents/Orders: Evaluate any exponentiation or order of operations (such as square roots) next.
 Multiplication and Division: Perform multiplication and division from left to right.
 Addition and Subtraction: Perform addition and subtraction from left to right.
 Fractions:
 A fraction represents a part of a whole. It has a numerator (top number) and a denominator (bottom number). For example, 3/4 represents three parts out of four.
 Fractions can be added, subtracted, multiplied, and divided following specific rules.
 Equality:
 The equals sign (=) denotes that two expressions have the same value.
These are just some of the basic mathematical rules. As you stay with this article, you will learn more advanced concepts and rules in mathematics. Practice regularly and seek further guidance from teachers or educational resources to enhance your understanding.

Basic To Algebra Expression
Let’s start with some basic concepts and move towards algebraic expressions.
 Numbers: Begin by understanding the different types of numbers, such as natural numbers (1, 2, 3…), whole numbers (0, 1, 2, 3…), integers (3, 2, 1, 0, 1, 2, 3…), rational numbers (fractions and decimals), and irrational numbers (such as √2 or π).
 Variables: Variables are symbols (usually letters) used to represent unknown quantities. Commonly used variables are x, y, and z.
 Arithmetic Operations: Review addition (+), subtraction (), multiplication (×), and division (÷).
 Expressions: An expression is a combination of numbers, variables, and arithmetic operations. For example, 3 + 2 is an expression. Expressions can also include parentheses and exponents. For example, (4 × 2) – 5² is an expression.
 Simplification: Simplifying an expression involves performing operations to reduce it to its simplest form. For example, simplifying 3x + 2x would involve combining like terms to get 5x.
 Order of Operations: Remember the acronym PEMDAS/BODMAS, which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This helps determine the order in which operations should be performed within an expression.
 Equations: Equations involve an equal sign (=) and express that two expressions have the same value. For example, 2x + 3 = 9 is an equation. To solve equations, you aim to find the value(s) of the variable that make the equation true.
 Translating Words to Algebraic Expressions: Practice translating word problems into algebraic expressions. For example, “twice a number increased by 5” can be represented as 2x + 5, where x represents the unknown number.
 Evaluating Expressions: Substitute specific values for variables and calculate the result. For example, if x = 3, evaluate the expression 2x + 4 as (2 × 3) + 4 = 10.
Signs Rules In Mathematics
Sign rules in mathematics are essential when working with arithmetic operations involving positive and negative numbers. Here are some key sign rules to keep in mind:
 Addition of Positive and Negative Numbers:
 When you add two numbers with the same sign (both positive and negative), you keep the sign and add the absolute values. For example: (+3) + (+5) = +8 and (4) + (2) = 6.
 When you add two numbers with different signs, you subtract the smaller absolute value from the larger one and use the sign of the number with the larger absolute value. For example: (+5) + (3) = +2 and (4) + (+7) = +3.
 Subtraction of Positive and Negative Numbers:
 Subtraction is the same as adding the opposite. To subtract a number, change the sign and perform addition. For example: (+5) – (+3) is the same as (+5) + (3) = +2.
 Multiplication and Division of Positive and Negative Numbers:
 The product of two numbers with the same sign is positive. For example: (+4) × (+2) = +8 and (3) × (2) = +6.
 The product of two numbers with different signs is negative. For example: (+4) × (2) = 8 and (3) × (+2) = 6.
 When dividing two numbers with the same sign, the quotient is positive. For example: (+10) ÷ (+2) = +5 and (12) ÷ (3) = +4.
 When dividing two numbers with different signs, the quotient is negative. For example: (+10) ÷ (2) = 5 and (12) ÷ (+3) = 4.
 Negative Numbers and Exponents:
 When an even number of negative signs is raised to an exponent, the result is positive. For example: (2)² = +4 and (3)⁴ = +81.
 When an odd number of negative signs is raised to an exponent, the result is negative. For example: (2)³ = 8 and (3)⁵ = 243.
It’s crucial to apply these sign rules correctly when performing mathematical operations to obtain accurate results. Practice working with positive and negative numbers, and become familiar with the sign rules to build a strong foundation in mathematics.
Basic Geometry
 Points, Lines, and Planes:
 Point: A point is a location in space and has no size or dimensions.
 Line: A line is a straight path with no endpoints that extends infinitely in both directions.
 Plane: A plane is a flat, twodimensional surface that extends infinitely in all directions.
 Angles:
 Angle: An angle is formed when two rays share a common endpoint called the vertex.
 Types of Angles: Acute angle (less than 90 degrees), Right angle (exactly 90 degrees), Obtuse angle (greater than 90 degrees), and Straight angle (exactly 180 degrees).
 Triangles:
 Triangle: A triangle is a polygon with three sides and three angles.
 Types of Triangles: Equilateral triangle (all sides and angles are equal), Isosceles triangle (two sides and two angles are equal), Scalene triangle (all sides and angles are different), Right triangle (one angle is 90 degrees).
 Quadrilaterals:
 Quadrilateral: A quadrilateral is a polygon with four sides and four angles.
 Types of Quadrilaterals: Square (all sides and angles are equal), Rectangle (opposite sides are equal and all angles are right angles), Parallelogram (opposite sides are parallel), Rhombus (all sides are equal), Trapezoid (one pair of sides is parallel), Kite (adjacent sides are equal).
 Circles:
 Circle: A circle is a set of all points in a plane that are equidistant from a fixed point called the center.
 Radius: The radius is the distance from the center of a circle to any point on its circumference.
 Diameter: The diameter is the distance across a circle passing through the center. It is twice the length of the radius.
 Circumference: The circumference is the distance around the outer boundary of a circle. It is calculated using the formula C = 2πr, where r is the radius and π is a mathematical constant approximately equal to 3.14159.
 Area: The area of a circle is given by the formula A = πr², where r is the radius.
These are just a few fundamental topics in basic geometry. As you explore further, you’ll encounter concepts like polygons, solid shapes (such as cubes, spheres, and cylinders), symmetry, congruence, and more. Practice solving problems and applying geometric principles to enhance your understanding of basic geometry.
