Key Concepts
The final position after two movements
The final position after two movements is found by adding the two movements. If movements are rightward, they are positive; if leftward, they are nega
Difference is defined as first number
Difference is defined as first number minus second number. Order matters, so 18 - 7 = 11 but 7 - 18 = -11.
The additive inverse of 18
The additive inverse of 18 is -18, and the additive inverse of -18 is 18. Subtracting a number is the same as adding its additive inverse.
Positive and negative tokens cancel each
Positive and negative tokens cancel each other as zero pairs. For example, 7 - 18 is handled by adding enough zero pairs and removing 18 positive toke
Positive multiplication means placing tokens into
Positive multiplication means placing tokens into a bag. Negative multiplication means removing tokens from a bag. Examples include 4 × (-2) = -8, (-4
