Study Notes
Mathematical Notation
Indices
Indices refer to the use of powers or exponents in mathematics. They indicate the degree to which one quantity is raised in relation to another. For example, 2^3 represents 2 raised to the power of 3, which equals 8. Indices can also be negative, such as -2^(-3), representing the inverse of 2 raised to the power of -3.
Extended Notation
Extended notation refers to the use of special symbols or notations to denote particular mathematical concepts. These may include symbols for integrals (∫), partial derivatives (∂), and vector operations (•). Such extended notation helps organize and structure mathematical thought and makes calculations easier.
Scientific Notation
Scientific notation is a method of expressing very large or very small numerical quantities as a power of ten times an ordinary decimal number. It follows the form a × 10^n, where a is a number between 1 and 10 (including 1 and 0) and n is an integer. This notation is commonly used in scientific contexts, providing a compact and efficient way to deal with large or small values.
BEDMAS
BIDMAS, also known as PEMDAS, stands for Brackets, Indices/Exponents, Division and Fractions, Multiplication and Addition/Subtraction. It is a mnemonic device used to remember the order of operations in mathematics. According to BIDMAS, brackets are done first, followed by powers and indices, division and fractions, and finally multiplication and addition from left to right.
Number Lines
Number lines are graphical representations of the number line concept. A number line consists of a straight line that represents the real number line. Dots along the line correspond to integers, while number labels correspond to specific rational numbers. By placing points on the line, comparing lengths, and counting dots, students can develop an understanding of numbers and their magnitudes.
