Study Notes
Numbers and Operations
- Integers: Whole numbers, either positive, negative, or zero (e.g.,..., -3, -2, -1, 0, 1, 2, 3,...)
- Operations on Integers: Addition, subtraction, multiplication, and division of integers, including rules for multiplication and division of integers with same/different signs
- Properties of Operations: Commutative, associative, and distributive properties of addition and multiplication
Fractions and Decimals
- Fractions: A way to represent part of a whole, written as a/b, where a is the numerator and b is the denominator
- Types of Fractions: Proper fractions ( numerator < denominator), improper fractions (numerator ≥ denominator), and mixed fractions (whole number and a proper fraction)
- Operations on Fractions: Addition, subtraction, multiplication, and division of fractions, including equivalent fractions and simplest form
- Decimals: Fractions with denominators as powers of 10, written as a decimal point followed by digits (e.g., 0.5, 3.14)
Algebra
- Variables and Expressions: Letters or symbols used to represent unknown values, and expressions involving variables and constants
- Simple Linear Equations: Equations with one variable, including solving equations with addition, subtraction, multiplication, and division
- Inequalities: Statements with greater than, less than, greater than or equal to, or less than or equal to, and their representations on a number line
Geometry
- Points, Lines, and Planes: Basic concepts, including collinear and non-collinear points, and intersecting and non-intersecting lines
- Angles and Pairs of Angles: Types of angles (acute, obtuse, right, straight), and pairs of angles (complementary, supplementary, adjacent)
- Properties of 2D Shapes: Number of sides, vertices, and angles of various shapes, including triangles, quadrilaterals, and polygons
Data Handling
- Data and Graphs: Collecting, organizing, and representing data using pictographs, bar graphs, and histograms
- Measures of Central Tendency: Mean, median, and mode of a data set, and their calculation and interpretation
Mensuration
- Perimeter and Area: Calculation of perimeter and area of various shapes, including triangles, quadrilaterals, and polygons
