It's called the inner product or the scalar product.

The formula for the inner product of two vectors involves multiplying their corresponding components and summing the results.
Synonyms

Morphology
The parts 'inner' (inside/within) and 'product' (result of multiplication) give a partial clue: the expression refers to a multiplication-like operation between components of vectors. However, the precise mathematical meaning (the dot/sum-of-products operation on vectors) is specialized and not fully predictable from the words alone for an average B1 learner, so it is only partially transparent.
Etymology
The term inner product comes from a simple image: take two arrows or lists of numbers, multiply each matching pair (the product) and then add those results that come from the 'inner' parts of the arrows (the inner). This gives a single 'number' that shows how much the two arrows point the same way, so the phrase means a way to get a number from two lists or arrows.
