(−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

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

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

−30−(−6)−(−6)−(−6)−(−6)−(−6)=−30−5(−6)=0

Elaine used the subtraction algorithm to subtract −17−(−3). She got the answer −14, but she does not feel confident that she is correct. Connect the expression −17−(−3) to a two-color counter model. Explain how the two-color counter model can be used to confirm whether Elaine’s answer is correct.(2 points)

To represent the expression −17−(−3) using a two-color counter model, we start with 17 black counters to represent -17. Then, we subtract 3 white counters to represent the subtraction of -3.

If Elaine's answer of -14 is correct, then the final count of the two-color counters should be -14. We can count the total number of counters in the model and observe if it matches -14.

If the result is indeed -14, it confirms that Elaine's answer is correct. However, if the count of the counters does not match -14, then Elaine's answer is incorrect.

To represent the expression −17−(−3) using a two-color counter model, we can start with 17 red counters to represent -17 and subtract 3 blue counters to represent the subtraction of -3.

If Elaine's answer of -14 is correct, then the final count of the two-color counters should be -14. We can count the total number of counters in the model and observe if it matches -14.

In the two-color counter model, each red counter represents a negative value and each blue counter represents a positive value. Adding or removing blue counters represents increasing or decreasing the overall value, while adding or removing red counters represents decreasing or increasing the overall value.

By counting the total number of counters in the model and evaluating their colors, we can determine the final result. If the count of red and blue counters matches -14, then Elaine's answer is correct. However, if the count does not match -14, then Elaine's answer is incorrect and further calculation or double-checking is needed.
