Topics in Introduction to Negative Numbers
Understanding Integers
- Whole numbers (0, 1, 2, 3...) and their negative counterparts (-1, -2, -3...) together form integers.
- Integers include positive numbers, negative numbers, and zero.
- Zero is neither positive nor negative.
Number Line and Ordering of Integers
- A number line helps us visualize integers. Zero is in the middle, positive numbers go to the right, and negative numbers to the left.
- On a number line, numbers increase as we move to the right and decrease as we move to the left.
- Any positive number is greater than any negative number.
Addition and Subtraction of Integers
- When adding two integers with the same sign, add their values and keep the common sign.
- When adding integers with different signs, subtract the smaller value from the larger one and keep the sign of the larger number.
- Subtracting an integer is the same as adding its opposite.
Real-Life Applications
- Negative numbers are used to show loss, debt, cold temperatures, and depths below sea level.
- Profit is positive, loss is negative.
- Temperatures above 0°C are positive, below 0°C are negative.
