dot or dotP or dotprod or scalar_product or
scalarProduct or the infixed operator * takes as argument
two vectors.
dot or dotP or dotprod or scalar_product or
scalarProduct or * returns the scalar product of these
two
vectors.

Output :
Indeed 25=1*4+2*3+3*5.
Note that * may be used to find the product of two polynomials represented as list of their coefficients, but to avoid ambiguity, the polynomial lists must be poly1[...].
