Study Notes
Understanding Integers
-
Absolute Value: The absolute value of an integer is its distance from zero on the number line, disregarding its sign.
-
Comparative Values:
- For positive integers, the larger absolute value indicates a larger integer.
- For negative integers, the smaller absolute value indicates a larger integer.
- Positive integers are greater than negative integers.
-
Number Line Representation:
- Positive integers are to the right of zero (origin), while negative integers are to the left.
- Numbers increase as you move from left to right.
Integer Operations
-
Addition Rules:
- Adding two positive integers results in a positive integer.
- Adding two negative integers results in a negative integer.
- Adding a positive and a negative integer results in a positive integer if the positive has a greater absolute value, or a negative integer if the negative has a greater absolute value.
- Equal absolute values of opposite signs yield zero.
-
Subtraction Method: Subtracting an integer can be performed by adding the integer's opposite sign.
-
Combining Multiple Integers: Sum positive integers and negative integers separately before combining the results.
Multiplication and Division of Integers
-
Multiplication Principles:
- The product of two integers with the same sign is positive.
- The product of two integers with opposite signs is negative.
-
Multiplied by Zero: Any integer multiplied by zero is zero, while multiplied by one remains unchanged.
-
Product of Multiple Integers: The product can be calculated by multiplying any two integers first, then the result with the third integer.
-
Division Principles:
- Dividing integers of the same sign results in a positive quotient.
- Dividing integers of opposite signs results in a negative quotient.
Exercises and Evaluation
- Absolute Values Exercise: Practice finding the absolute values of given integers.
- Evaluative Expressions: Solve expressions using absolute values and basic operations.
- Comparative Exercises: Fill in blanks comparing integers, practicing inequality symbols.
Summary of Integer Values
- Provide lists of integers within specific ranges.
- Write integers in order, both ascending and descending.
Key Integer Operations Examples
- Addition Examples: Compute results of adding positive and negative integers.
- Multiplication Examples: Show results of multiplying integers of various signs.
- Division Examples: Solve simple division problems with positive and negative integers.
