## What does an equals sign with three lines mean?

A symbol with three horizontal line segments ( ) resembling the equals sign is used to denote both equality 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 readers of analog clocks).

## What is the sign for approximately equal to?

Symbols based on equality x ≈ y means x is approximately equal to y. This may also be written ≃, ≅, ~, ♎︎ (Libra Symbol), or ≒. G ≈ H means that group G is isomorphic (structurally identical) to group H. (≅ can also be used for isomorphic, as described below.)

## What does the equal sign with a squiggle on top mean?

Approximate equality is a concept used primarily in physics and engineering, and also occasionally in mathematics. Two quantities are approximately equal when they are close enough in value so the difference is inconsequential in practical terms. Approximate equality is symbolized by a squiggly equal sign ( ).
