Minus – Definition with Examples

What is Minus?

Minus sign is used in mathematics for multiple representations. 

  • Subtraction operation

         Minus represents the arithmetic operation of subtraction between two numbers. For example,  

subtraction operation

Minus sign also means taking something away from a given value. 

For example, Darby has 6 gingerbread with her and she gives 3 gingerbread to Kelly. 

So 6 minus 3 is equal to 3. Darby is left with 3 gingerbread.

  • To represent negative integers

        The minus sign is used to represent negative integers, whole numbers less than zero (no fractions).

to represent negative integers

For representing a negative integer, add a negative sign in front of a whole number. 

For example, negative integer 3 is represented as: -3

  • Mathematical operations on integers using ‘Minus’ sign

        Multiplication of two negative numbers gives a positive. 

        Minus x Minus  = Positive

        For example,

         – 4 -10 = + 40

  • Use in measurement 

        For example, A temperature of  – 3˚ C means 3 degrees below zero.

        Another example, 

        The temperature is 4˚ C and then drops -10˚. What is the temperature now? 

         4 – 10 = -6

         The answer is -6˚C

  • To represent opposite directions

        We use the minus sign to represent a negative direction on a graph paper.
