miinusmerkkiä

Miinusmerkkiä, also known as the minus sign, is a symbol used in mathematics to indicate subtraction. It is typically represented by the character "-". The minus sign is placed between two numbers to indicate that the second number is to be subtracted from the first. For example, in the expression "5 - 3", the minus sign indicates that 3 is to be subtracted from 5, resulting in 2.

The minus sign is also used to denote negative numbers. A negative number is a number that is less than zero. It is represented by placing the minus sign in front of the number. For example, "-5" is a negative number, indicating a value that is 5 units less than zero.

In addition to its use in arithmetic, the minus sign has various other applications in mathematics and science. It is used in algebra to represent unknown quantities, in calculus to denote derivatives, and in physics to indicate negative values in equations. The minus sign is a fundamental symbol in many areas of mathematics and science, and its use is essential for understanding and communicating mathematical concepts.
