It is not displayed correctly.

The idea here was to create vectors. When we subtract two points (A - B), we obtain a vector that originates in point A and ends in point B.

Otherwise the subtraction itself is well defined, but when we subtract points, we want to see a vector, not a new point.

The subtitle is wrong. This is not Dot Product.

Also thing about schematically presenting the idea. Show how the second vector is moved into sam point as the first one, and which is the angle that gets calculated.
Also display the Mathematical formula that is used for calculating the angle and allow user to put parameters directly into the formula and allow user to select existing vectors from drop-down menu.

If possible use MathML as described here:

Display dot product as equation, where user can select existing vectors from drop-down menu and show the equation that is used for calculating the dot product.

Display length as equation, where user can select existing vectors from drop-down menu and show the equation that is used for calculating the dot product. It would be great to use MathML here as well.

Since length has the geometry meaning as well it would be nice to show that on graph on the left, for instance with dimension lines as is done on technical drawings.

The idea here was to schematically show how vectors are added. When we add two vectors show (with dotted line, or with another colour), how the second vector is placed at the end of first one and highlight the result (use different colour here as well).

Show addition as equation, where user can select existing vectors from drop-down menu.
