Perhatikan bahwa

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell PQ with rightwards arrow on top plus QR with rightwards arrow on top plus RP with rightwards arrow on top end cell equals cell open parentheses PQ with rightwards arrow on top plus QR with rightwards arrow on top close parentheses plus RP with rightwards arrow on top end cell row blank equals cell PR with rightwards arrow on top plus RP with rightwards arrow on top end cell row blank equals cell PP with rightwards arrow on top end cell end table end style 

Perhatikan bahwa vektor yang memiliki titik awal dan akhir yang sama merupakan vektor nol. Sehingga

begin mathsize 14px style PQ with rightwards arrow on top plus QR with rightwards arrow on top plus RP with rightwards arrow on top equals PP with rightwards arrow on top equals 0 with rightwards arrow on top end style

Karena panjang dari vektor begin mathsize 14px style 0 with rightwards arrow on top end style adalah 0, maka panjang vektor dari hasil penjumlahan undefined adalah 0.
