It might means that if you append the interval KS to the interval SB you obtain the interval KB. It might be that KS designates the length of the interval from K to S and similarly for the others. In either case from the statement KS+SB=KB I can conclude that K is to the left of S and S is to the left of B. Apply the same reasoning to the other two equations and see what that tells you about the placement of H, S, D, K and B. Finally what does the last sentence say about the placement of L? Penny
