Increment (delta)

Meaning and uses

The increment sign, a triangle that means a change in a value, as in ∆t for a change in time. It looks like the Greek capital delta but is a separate character for maths.

Unicode details

∆ is the Unicode character named INCREMENT, code point U+2206, in the Mathematical Operators block. It was added in Unicode 1.1 in 1993, and Unicode classes it as a maths symbol (general category Sm).

It is not an emoji, so it keeps the colour and size of the text around it.
