What ⊗ means

In algebra, ⊗ is the tensor product symbol. It combines mathematical spaces, vectors, or maps.

A math text from 1894 uses for a product; the path to circled ⊗ was still unresolved as of 2020.

Specialist math notation; surrounding context decides.

Do not assume ordinary multiplication.

Questions people ask

1

Why does ⊗ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
