Subtractions is a term used in mathematics to refer to the process of finding the difference between two numbers or quantities. It is a fundamental operation in arithmetic, alongside addition, multiplication, and division. When performing a subtraction, a smaller number is taken away from a larger number to determine what remains or on which the operation is performed.
Subtractions can be visualized as removing or diminishing a part from a whole, resulting in a decreased value. This operation can also be seen as finding out "how much less" one number is compared to another.
In mathematical notation, subtractions are often denoted with the minus sign (-) or the subtraction symbol (–). For example, in the equation 10 – 3 = 7, the value 3 is being subtracted from 10, resulting in the answer 7.
Subtraction can be performed using various methods, including mental calculation, using a number line, or by regrouping or borrowing in multiple-digit subtraction.
Subtractions have many practical applications in daily life, such as measuring differences, determining changes in quantities, calculating discounts, or finding the remaining amount after expenses or deductions.
In summary, subtractions refer to the mathematical operation of finding the difference between numbers or quantities by subtracting a smaller value from a larger one. It involves the removal or reduction of a portion from a whole, resulting in a decreased value or remaining amount.
