Study Notes
Rational Numbers
- Rational numbers can be expressed in the form p/q, where p and q are integers and q is not zero.
- Examples include 1/2, 3, -5/7, 0.
- All whole numbers and integers are rational numbers.
- Rational numbers are closed under addition, subtraction, and multiplication.
- Division by zero is not defined for rational numbers.
Properties of Numbers
- Closure: Whole numbers are closed under addition and multiplication. They are not closed under subtraction and division. Integers are closed under addition, subtraction and multiplication. They are not closed under division. Rational numbers are closed under addition and multiplication. But they are NOT closed under division; division by zero is not defined.
- Commutativity: Whole numbers are commutative under addition and multiplication. Integers and rational numbers are also commutative under addition and multiplication.
- Associativity: Whole numbers are associative under addition and multiplication. Integers and rational numbers are associative under addition and multiplication.
- Distributivity: Multiplication distributes over addition for whole numbers, integers, and rational numbers.
Linear Equations in One Variable
- An equation is a statement of equality.
- A linear equation in one variable is of the form ax + b = 0, where 'x' is the variable and 'a' and 'b' are constants (a≠0).
- Solving an equation means finding the value of the variable that makes the equation true.
- Transposing a term from one side of the equation to the other side changes its sign.
Understanding Quadrilaterals
- A polygon is a closed two-dimensional shape formed by line segments.
- A quadrilateral is a polygon with four sides.
- Convex polygons have all interior angles less than 180 degrees.
- Concave polygons have at least one interior angle greater than 180 degrees.
- Regular polygons have equal sides and angles, and irregular polygons have unequal sides and angles.
- The sum of interior angles of a polygon with 'n' sides is (n-2) x 180 degrees.
- The sum of exterior angles of a polygon is 360 degrees.
- Special quadrilaterals include parallelograms, rectangles, squares, rhombuses, and kites, each with specific properties concerning sides, angles, and diagonals.
Data Handling
- Data: Numerical observations.
- Frequency: The number of times an observation occurs.
- Frequency distribution: A table showing observations and their frequencies.
- Range: The difference between the highest and lowest observations.
- Class mark: The midpoint of a class interval.
- Histogram: A bar graph representing data in intervals.
- Pie chart: A circular graph showing data as proportions.
- Probability: The likelihood of an event occurring, always between 0 and 1.
Squares and Square Roots
- Square of n = n x n = n²
- A perfect square is a number which is the square of an integer.
- Finding the square root of a number is the inverse operation to squaring.
- √n represents the square root of n.
- Properties of squares—even/odd, ending in certain digits.
Cubes and Cube Roots
- Cube of n = n x n x n = n³
- A perfect cube is a number which is the cube of an integer.
- Finding the cube root of a number is the inverse operation to cubing.
- ∛n represents the cube root of n.
- Properties of cubes—(even/odd and ending in certain digits).
Comparing Quantities
- Discount = Marked Price - Selling Price
- Additional expenses = overhead expenses
- Sales tax: Tax % on bill amount
- VAT: Tax on selling price of an article
- Percent: Per hundred (hundredths)
Exponents and Powers
- Exponents represent repeated multiplications
- Laws of exponents.
Direct and Inverse Proportions
- Direct proportion: When one quantity increases, the other quantity increases proportionally.
- The ratio is constant
- Inverse Proportion: When one quantity increases, the other decreases proportionally.
- The product is constant
- The values can be found for unknown amounts in the equation
Factorization
- Factorization: Writing an expression as a product of factors.
- Greatest common factor(GCF): The largest number that divides all the terms.
- Factoring Binomials—Difference of Squares, perfect square trinomial (sum/difference)
- Common factors in polynomials
- Division of Polynomials: (remainder theorem)
Introduction to Graphs
- Coordinates on a plane (x and y axis).
- Origin (0,0)
- Bar graphs, Pie graphs, histograms, line graphs
- Plotting points and relations using graphs
Mensuration
- Perimeter, area of rectangles, squares, triangles, and quadrilaterals
- Area and circumference.
- Volume of cuboids and cubes
- Areas and volumes of other 3D shapes
- Relationship between angles and sides in shapes
- Area and perimeter formulas, calculation of unknown values, etc.
