miinuslukuja

Miinuslukuja, also known as negative numbers, are numbers less than zero. On a number line, they are located to the left of zero. For example, -1, -2, and -3 are all miinuslukuja. They are essential in mathematics and are used to represent various concepts, such as debt, temperature below freezing, or a decrease in value.

The concept of miinuslukuja allows for a complete number system where subtraction is always possible. For any two numbers a and b, a - b will always have a defined result within the set of integers, which includes both positive numbers, zero, and miinuslukuja. The magnitude of a miinusluku is its distance from zero, which is the same as the magnitude of its corresponding positive number. For instance, the magnitude of -5 is 5.

Operations involving miinuslukuja follow specific rules. Adding a miinusluku is equivalent to subtracting its positive counterpart. For example, 5 + (-3) is the same as 5 - 3, which equals 2. Subtracting a miinusluku results in addition. For example, 5 - (-3) is the same as 5 + 3, which equals 8. Multiplication and division of miinuslukuja also have defined rules: a negative number multiplied or divided by a positive number results in a negative number, while two negative numbers multiplied or divided result in a positive number.
