## What is Equal Sign?

The Equal sign is a sign of "Equality." Definition says that it is a mathematical symbol that is used to show equality in a distinct sense. So mathematically speaking, whenever we try to show equality between two expressions, we tend to "equate" the two items. Hence, the equal sign is the sign that helps us to mathematically show equality between two symbols.

## What is the Symbol of Equal to Sign

The symbol used to show the equal to sign is $$=$$ (two parallel horizontal lines). This symbol is only used when the two quantities to be compared are exactly the same. There are different symbols for each comparison aspect.

Click on the comparison aspects given here to know the symbols that are used.

Here is a list of some of the most commonly used comparison terms and their meanings:

Comparison Meaning
Equal to  Exactly the same
Not equal to Not exactly the same

## Use of Equal to Sign in An Equation

The symbol of equal to is used to show the exact same amount of any two different quantities. For example, if we know that the price of 1 pound of meat is exactly \$3, we can say that

Price of 1 pound of meat $$=3$$

Keep in mind here that only exact values are to be given when using the equal to sign.
