Pembahasan

Kita dapat langsung menghitung dari setiap operasi vektor tersebut:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 2 a with rightwards arrow on top plus b with rightwards arrow on top minus 3 c with rightwards arrow on top end cell equals cell 2 open parentheses table row 4 row 3 end table close parentheses plus open parentheses table row cell negative 2 end cell row 3 end table close parentheses minus 3 open parentheses table row 1 row 5 end table close parentheses end cell row blank equals cell open parentheses table row 8 row 6 end table close parentheses plus open parentheses table row cell negative 2 end cell row 3 end table close parentheses minus open parentheses table row 3 row 15 end table close parentheses end cell row blank equals cell open parentheses table row cell 8 minus 2 minus 3 end cell row cell 6 plus 3 minus 15 end cell end table close parentheses end cell row blank equals cell open parentheses table row 3 row cell negative 6 end cell end table close parentheses end cell end table end style

Jadi, hasil dari begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank 2 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell a with rightwards arrow on top end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank plus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell b with rightwards arrow on top end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank minus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 3 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell c with rightwards arrow on top end cell end table end style adalah begin mathsize 14px style open parentheses table row 3 row cell negative 6 end cell end table close parentheses end style
