## 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, 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). 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 • To represent opposite directions

We use the minus sign to represent a negative direction on a graph paper. It also runs in the negative direction.
