"Swapping the terms does not change the sum when both the terms are negative numbers".
Can you explain why this is happening using the Token Model of integers that we saw in the class \(6\)?
[Token Model: Each '\(+\)' press adds a red (positive) token, each '\(–\)' press adds a green (negative) token.]
Take \(-3\) and \(-6\) to explain.
\((-3)\) \(+\) \((-6)\) \(=\)
\((-6)\) \(+\) \((-3)\) \(=\)
