Meaning of Infinity Symbol in Maths

In mathematics, infinity is an idea, not an ordinary number. You cannot reach it by counting, and you cannot add 1 to it and get something bigger. Here is how the symbol of infinity is used in school and college maths:

UseExampleRead as
Limitslim (1/x) = 0 as x → ∞as x grows without end, 1/x gets close to 0
Intervalsx ∈ [0, ∞)x is 0 or any positive number
Infinite series1/2 + 1/4 + 1/8 + ... = 1the sum of infinitely many terms is 1
Setsthe natural numbers are infinitethey never run out
Negative side(−∞, 5)every number less than 5

Two points students often get wrong:

  • 1/0 is not ∞. Division by zero is undefined.
  • ∞ − ∞ and ∞/∞ are not 0 or 1. They are called indeterminate forms, and you must solve the limit to find the answer.

Also note: an infinity bracket is always round, like [0, ∞), never square, because infinity is never actually reached. For other maths signs see the full math symbols list.

Love Infinity Symbol and Forever Meanings

Outside maths, ∞ has become a popular sign of things that should never end. The common meanings are:

  • Eternal love: couples use a love infinity symbol, often joined with a heart, to mean "love forever". A heart infinity symbol in text can be as simple as ∞❤ or ❤∞.
  • Friendship: best friends write "friends ∞" or "BFF ∞".
  • Family and memory: people use it to remember someone they miss.
  • Infinity symbol spiritual meaning: many people see the endless loop as a sign of the soul, of balance between two sides, or of life without beginning or end. These are personal and cultural beliefs, and they vary from person to person.

Some modern artists also combine a trishul or Om with a loop, and a Shiv Shakti symbol with infinity is a design you may see on pendants and wall art, meant to show the union of the two as endless. See our Om symbol and trishul symbol pages for their traditional meanings, and love symbols for more heart signs.

Infinity Symbol in Jewellery: Ring, Bracelet, Chain

Because it means forever, ∞ is a favourite shape for jewellery. You will often see an infinity symbol ring for engagements and anniversaries, infinity bracelets and chains as friendship gifts, pendants and lockets, and modern mangalsutra designs with an infinity loop in the centre.

Another well-known design is the rose anchor infinity symbol. Each part is usually given a meaning: the rose for love, the anchor for staying strong and steady, and the loop for forever. When you write a message for such a gift, you can paste the text symbol, for example "Always yours ∞".

⧞Infinity with a vertical barrare maths sign, not for decoration
ꝏLatin small letter ooa letter used in some old writing; not infinity

The ♾️ emoji was first a symbol for "permanent paper" (paper that lasts a long time), which is why its official Unicode name is Permanent Paper Sign. Today it is used as the forever symbol emoji.

Where the Infinity Symbol Came From

The English mathematician John Wallis introduced ∞ as a maths symbol in 1655. Why he chose this shape is not known for certain. The curve itself is called a lemniscate, from a Latin word for a ribbon, because it looks like a ribbon tied in a loop.

For more signs from maths class, see the square root symbol, plus-minus symbol and degree symbol pages.
