Furthermore, BuildAMol introduces a unique operator-based syntax called "Molecular Arithmetics." This user-friendly syntax allows intuitive molecule assembly: addition (+) facilitates combining fragments, subtraction (-) enables the removal of substructures like atoms or residues, and multiplication (*) allows for the construction of regular polymers, offering a valuable short-hand notation to accelerate the modeling for users who do not wish or require more elaborate customization in their assembly workflow.
