Understanding the Basics of Positive and Negative Numbers
Positive and negative numbers are a fundamental concept in mathematics, and mastering them is essential for solving various mathematical problems. In this article, we will explore the basics of positive and negative numbers, their properties, and provide tips and worksheets to help you easily master them.
What are Positive and Negative Numbers?
Positive numbers are numbers that are greater than zero, represented by a plus sign (+) or no sign at all. Examples of positive numbers include 5, 10, and 20. Negative numbers, on the other hand, are numbers that are less than zero, represented by a minus sign (-). Examples of negative numbers include -5, -10, and -20.
Properties of Positive and Negative Numbers
Here are some essential properties of positive and negative numbers that you should know:
- Addition: When you add two positive numbers, the result is always positive. When you add two negative numbers, the result is always negative. When you add a positive and a negative number, the result depends on the magnitude of the numbers. If the positive number is larger, the result is positive. If the negative number is larger, the result is negative.
- Subtraction: When you subtract a positive number from another positive number, the result is always positive. When you subtract a negative number from another negative number, the result is always negative. When you subtract a positive number from a negative number, the result is always negative.
- Multiplication: When you multiply two positive numbers, the result is always positive. When you multiply two negative numbers, the result is always positive. When you multiply a positive and a negative number, the result is always negative.
- Division: When you divide a positive number by another positive number, the result is always positive. When you divide a negative number by another negative number, the result is always positive. When you divide a positive number by a negative number, the result is always negative.
