Study Notes
Basic Arithmetic
- Basic arithmetic involves fundamental operations like addition, subtraction, multiplication, and division applied to numbers.
- These operations form the foundation for more complex mathematical concepts.
- Understanding these operations is crucial for many everyday tasks and problem-solving.
Negative Numbers
- Negative numbers are numbers less than zero.
- They are used to represent quantities in situations where a quantity falls below a reference point (zero).
- Examples include temperatures below freezing point, debts, and losses.
- Negative numbers are represented with a minus sign (-) preceding the number (e.g., -5).
Number Line Representation
- A number line is a visual representation of numbers.
- It displays numbers in a sequential order along a straight line.
- Numbers increase from left to right.
- Zero is typically located at the center of the line.
- Positive numbers are positioned to the right of zero, and negative numbers to the left.
- The number line helps visualize the relative magnitudes and order of numbers.
- It also demonstrates the concept of numerical distance and direction.
Order of Operations
- The order of operations (PEMDAS/BODMAS) specifies the sequence in which calculations are performed in arithmetic expressions.
- Parentheses (or brackets): Evaluate expressions within parentheses first.
- Exponents (or orders): Calculate expressions with exponents next.
- Multiplication and Division: Perform multiplication and division from left to right.
- Addition and Subtraction: Perform addition and subtraction from left to right.
- This order ensures that calculations are performed in a consistent way, eliminating ambiguity and producing reliable results.
- Misapplication of order of operations leads to errors in calculations.
Integer Operations
- Integers are whole numbers (positive, zero, or negative).
- Operations with integers involve addition, subtraction, multiplication, and division.
- Addition of integers: Adding two integers with the same sign involves adding the absolute values and keeping the same sign. Adding two integers with different signs involves finding the difference of the absolute values and using the sign of the greater absolute value.
- Subtraction of integers: Subtracting two integers is equivalent to adding the opposite of the second integer.
- Multiplication and Division of integers: Multiplying/dividing integers with the same signs result in a positive product/quotient. Multiplying/dividing integers with different signs result in a negative product/quotient.
- Rules for negative numbers need to be followed when performing integer operations.
