state 0

    INTEGER	shift, and go to state 1

    line	go to state 8
    exp 	go to state 2



state 1

    exp  ->  INTEGER .   (rule 4)

    $default	reduce using rule 4 (exp)



state 2

    line  ->  exp . EOL   (rule 1)
    exp  ->  exp . '+' exp   (rule 2)
    exp  ->  exp . '-' exp   (rule 3)

    EOL 	shift, and go to state 3
    '+' 	shift, and go to state 4
    '-' 	shift, and go to state 5



state 3

    line  ->  exp EOL .   (rule 1)

    $default	reduce using rule 1 (line)



state 4

    exp  ->  exp '+' . exp   (rule 2)

    INTEGER	shift, and go to state 1

    exp 	go to state 6



state 5

    exp  ->  exp '-' . exp   (rule 3)

    INTEGER	shift, and go to state 1

    exp 	go to state 7



state 6

    exp  ->  exp . '+' exp   (rule 2)
    exp  ->  exp '+' exp .   (rule 2)
    exp  ->  exp . '-' exp   (rule 3)

    '+' 	shift, and go to state 4
    '-' 	shift, and go to state 5

    '+' 	[reduce using rule 2 (exp)]
    '-' 	[reduce using rule 2 (exp)]
    $default	reduce using rule 2 (exp)



state 7

    exp  ->  exp . '+' exp   (rule 2)
    exp  ->  exp . '-' exp   (rule 3)
    exp  ->  exp '-' exp .   (rule 3)

    '+' 	shift, and go to state 4
    '-' 	shift, and go to state 5

    '+' 	[reduce using rule 3 (exp)]
    '-' 	[reduce using rule 3 (exp)]
    $default	reduce using rule 3 (exp)



state 8

    $   	go to state 9



state 9

    $   	go to state 10



state 10

    $default	accept
