Compare with vector product Also called dot product
Example sentencesExamples
The first scalar product could have told us that one of the digits was 6 too small but then no sensible answer would have been obtainable from the second scalar product.
To judge this number, note that the scalar product between uncorrelated motions follows a Gaussian distribution of 0.015 half-width.
The scalar product also appears in Grassmann's 1844 work.
