Subtraction is a fundamental arithmetic operation in mathematics that involves finding the difference between two numbers or quantities. It is the process of removing or taking away a certain value or quantity from another. Subtracting involves finding out how much one number is smaller than another. It is denoted by the "-" symbol, often referred to as the minus sign.
When subtracting, the number being deducted is referred to as the subtrahend, while the number being taken away from is called the minuend. The result of the subtraction is called the difference. For example, in the equation 10 - 4 = 6, the subtrahend is 4, the minuend is 10, and the difference is 6.
Subtraction can be performed using several methods, including the traditional column method, number line method, or mental calculation. In the column method, numbers are aligned vertically with the units, tens, hundreds, etc. lined up, and subtraction is carried out digit by digit, starting from the right. In the number line method, a line is drawn and marked with the numbers being subtracted, and the difference is found by counting backward. Subtraction can also be done mentally by using various strategies such as regrouping or breaking numbers into easier parts.
Overall, subtraction allows us to find the difference or how much is left after removing one quantity from another, making it an essential concept in mathematics and daily life.

The word "subtraction" has its etymological roots in the Latin word "subtrahere", which is a combination of the prefix "sub-" (meaning "from under") and the verb "trahere" (meaning "to draw" or "to take away"). Thus, "subtrahere" means "to draw or take away from under". From Latin, the word entered Middle English as "subtraction", preserving its meaning as the mathematical operation of taking away or deducting one number from another.
