The dot product of two vectors is the sum of the products of the equivalent elements of the vectors
→ (2 4) ⋅ (1 -2) = 2×1 + 4×-2 = 2 - 8 = -6

You do the dot product of the vectors by multiplying their corresponding coordinates and adding them up altogether. For instance: <1,2,3> ∙ <-3,4,-1> = 1(-3) + 2(4) + 3(-1) = -3 + 8 - 3 = 2
It need not be. 1/2 + 1/4 = 3/4 1/2 * 1/4 = 1/8
The product is less than or greater than the whole number depending on the sign of the fraction.(1/2) * 4 = 2, which is smaller than 4.(1/2) * -4 = -2, which is smaller than 4.(-1/2) * 4 = -2, which is smaller than -4.(-1/2) * -4 = 2, which is greater than -4.
The product of the square of 1/2 and the sum of 13 and 19 is 169/4.
(1/2*-1/4)*(5x^2-2x+6) = -0.625x^2+0.25x-0.75
