(Fourteen and Fifteen) Integers,[1] also referred to as Numbers by fans, are a species of sentient colorful numbers in the genus Algebraliens. The most notable members of this species (and the only ones with meaningful canonical appearances in BFDI) are Four and Two.

In BFB, Integers appear to be more sloppily hand-drawn figures of their symbol. Unlike normal characters, Integers are hand-drawn. They are drawn with a thick black outline, with one uniform color. They all have eye-widening compared to the characters. Their arms and legs are also different, being drawn with width and usually a lighter color than their body. The front and back views of their bodies are the same, even if vertically asymmetric. The only difference is the lack of a face. An integer with a hole in it (such as 0 and 6) will be covered with its color.

In "X Finds Out His Value" however, Integers appear to be more geometrical, amimated using rigs with straight lines and curves.

Integers seem to share a close relationship with one another, rather with non-math symbols, sticking to their own society.

Integers have many simple activities they may consider hobbies. These activities are:

Numbers seem to be more flexible than objects. Being round and bulbous, numbers seem to be made out of a squishy material. From character to character, the material varies. Four has squishy material (as seen in BFB 1 when Liy squished him), Seven is made of rubber material (as seen in "Thanks for 900,000 subscribers!"), and Eight is very solid, rumored to be made of pure lead (mentioned by Six in "Thanks for 900,000 subscribers!"). The rest of the number's materials are unknown. Numbers are also said to not have gender "where [they] come from" (mentioned by Four in "Enter the Exit"), most using any pronouns. They are also covered in "numeric membrane" (as Coiny implied in BFB 17), which is an analogue for skin.

Numbers seem to have a range of abilities, greatly differing from regular objects.

These include:

Numbers differ in abilities, some being weaker than others. Four has most of the abilities listed. Two has the ability to give their powers to others, though if the other numbers can is unknown.

Numbers are able to perform mathematical operations with each other, and other sufficiently number-like objects or formations. In "Four Goes Too Far", Four is multiplied with Donut (representing 0), with X meant to be a multiplicative sign, but ran away out of fear. In "Thanks for 1,500,000 Subscribers!!", Nine and Six use a plus shaped bush to combine into Fifteen.
