(−6)+(−6)+(−6)+(−6)+(−6)=5(−6)=−30
left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis equals 5 left parenthesis negative 6 right parenthesis equals negative 30
−30−(−6)−(−6)−(−6)−(−6)−(−6)=−30−5(−6)=0
negative 30 minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis equals negative 30 minus 5 left parenthesis negative 6 right parenthesis equals 0
30−6−6−6−6−6=30−5(6)
30 minus 6 minus 6 minus 6 minus 6 minus 6 equals 30 minus 5 left parenthesis 6 right parenthesis
(−5)+(−5)+(−5)+(−5)+(−5)+(−5)=6(−5)=−30

left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis plus left parenthesis negative 6 right parenthesis equals 5 left parenthesis negative 6 right parenthesis equals negative 30
−30−(−6)−(−6)−(−6)−(−6)−(−6)=−30−5(−6)=0
negative 30 minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis minus left parenthesis negative 6 right parenthesis equals negative 30 minus 5 left parenthesis negative 6 right parenthesis equals 0
30−6−6−6−6−6=30−5(6)
30 minus 6 minus 6 minus 6 minus 6 minus 6 equals 30 minus 5 left parenthesis 6 right parenthesis
(−5)+(−5)+(−5)+(−5)+(−5)+(−5)=6(−5)=−30
The model that can be used to represent −30÷−6 is (−5)+(−5)+(−5)+(−5)+(−5)+(−5)=6(−5)=−30.
