Equal
Two quantities are said to be equal if they are, in some well-defined sense, equivalent. Equality of quantities 
and
is written 
.
A symbol with three horizontal line segments (
) resembling the equals sign is used to denote bothequality by definition (e.g., 
means 
is Defined to be equal to 
) and Congruence(e.g., 
means 13 divided by 12 leaves a Remainder of 1--a fact known to all readersof analog clocks).
