Integers are whole numbers that include positive numbers, negative numbers, and zero. They are used to represent quantities, ordering, and calculations. Understanding integers helps build strong foundations in arithmetic, algebra, and real-life problem solving.
Fractions are solved by finding common denominators, converting to like fractions, and then applying operations like addition, subtraction, multiplication, or division. Simplifying the final result gives the answer in its lowest possible form.
BODMAS is a rule that defines the order of operations: Brackets, Orders, Division, Multiplication, Addition, and Subtraction. It ensures correct calculation of expressions by following a fixed sequence to avoid errors in solving problems.
Percentage is calculated by dividing the part by the whole and multiplying by 100. It is used to express proportions, compare values, and solve real-world problems involving discounts, profit, loss, and financial analysis.
Factors are numbers that divide a given number exactly, while multiples are results obtained by multiplying that number. Understanding factors and multiples helps in finding HCF, LCM, and solving divisibility and number system problems.
