What we have learnt
- The real number system consists of rational and irrational numbers, each having unique properties and operations.
- Understanding and manipulating fractions, decimals, and percentages are fundamental skills for solving everyday problems.
- Financial mathematics provides practical applications of number operations in real-life scenarios such as simple interest calculations and currency exchanges.
Key Concepts
- -- Rational Numbers
- Numbers that can be expressed as the quotient of two integers, where the denominator is not zero.
- -- Irrational Numbers
- Numbers that cannot be expressed as a simple fraction, with non-repeating, non-terminating decimal expansions.
- -- Exponents
- A mathematical notation indicating the number of times a number is multiplied by itself.
- -- Standard Form
- A way of expressing numbers that facilitates comparison and operations, especially for very large or small values.
- -- Proportions
- An equation that states two ratios are equal, crucial for solving a variety of real-world problems.
