Suppose we purchase ice cream for a certain amount of money, say $140, and we give $200 to the cashier. Now, the cashier returns the excess amount by performing subtraction such as 200−140=60. Then, the cashier will return $60. What is exactly happening here? The answer to this question is subtraction.
Subtraction is one of the four basic arithmetic operations in mathematics. The other three being addition, multiplication, and division. We can observe the applications of subtraction in our day-to-day life in different situations. For example, if we have 3 candies and our friend asks us for 1 candy, how many candies are we left with? Simply, 3−1=2...
The operation or process of finding the difference between two numbers or quantities is known as subtraction.To subtract a number from another number is also referred to as ‘taking away one number from another’. Some instances where we use subtraction are while making payments, transferring money to our friends and many more.
In mathematics, we have generally used different symbols for different operators. We have symbols like +,−,/,∗ and many more. The subtraction symbol “−” is one of the most important math symbols that we use. In the above section, we read about subtracting two numbers 6 and 3. If we observe this expression: (6−3=3), the symbol (−) between the two nu...
When we subtract two numbers, we commonly use some terms that are used in a subtraction expression: Minuend: A minuendis the number from which the other number is subtracted. Subtrahend: A subtrahendis the number which is to be subtracted from the minuend. Difference: A differenceis the final result after subtracting the subtrahend from the minuend...
Minus is a sign or a symbol that is represented by a horizontal line. We use minus in mathematics for multiple representations.
Subtraction Operation
Minus represents the arithmetic operation of subtraction between two numbers. We use minus sign to denote subtract, decreased by, take away, etc. For example, Minus sign also means how much is one value more than the other value. For example, Darby has 8 gingerbread with her and Olive has 3 gingerbreads. Darby has more gingerbreads by (8−3)=5
To Represent Negative Integers
Integers are the numbers that are not in decimal or fractional form and include positive and negative numbers along with 0. We use the minus sign to represent the negative integers, i.e., the whole numberswhich are less than zero (no fractions). For representing a negative integer, we add a negative or minus sign in front of a whole number. For example, negative integer 5 is represented as: (−5)
Use in Measurement
We also use the minus sign in measurement specially in temperature. For example, a temperature of −4∘Cmeans 4 degrees below zero. Another example: The temperature is 5∘C and then drops −10∘C. What is the temperature now? The temperature now =5−10=−5∘C
Regrouping in mathcan be defined as the process of making/breaking groups when carrying out operations like addition and subtraction. To regroup means to rearrange groups in place value to carry out an operation. We use regrouping in subtraction, when digits in the minuend are smaller than the digits in the same place of the subtrahend. This proces...
In subtraction, we sometimes use the concept of regrouping between numbers. When the numbers are subtracted using the column method and the bottom digit is greater thanthe upper digit, we regroup the numbers to be able to subtract. Let us understand subtraction using this regrouping example, which includes finding the answer to the expression 31−19...
Here are a few important properties of subtraction in our everyday life. 1. Commutative property of subtraction: Commutative propertystates that swapping of numbers does not alter the result. But in subtraction, we cannot get the same output when we put minuend in place of subtrahend and vice versa. Hence, commutative property is not possible in ca...

The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math.

This is the first use of the minus sign we all learn in kindergarten or first grade – i.e. to denote the difference or how far a value is from another.
- As a Label for Negative Numbers. The second time we see the minus sign is when we learn about negative numbers or numbers that are on the left side of the zero on the number line.
- As a “Flip” Operation. Soon after we learn about negative numbers, we would learn about the third meaning of the minus sign – the “flip” over zero. For a positive quantity or expression, the minus sign flips it across zero on the number line.
Among the most universally recognized symbols in mathematics is the − symbol, representing the "Minus Sign". This simple yet profound symbol finds application across a spectrum of mathematical operations and contexts.

The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5.
