Answer 2

Thank you for sharing your own work.

Note that both -$17 and -$164 are negative. Which one are you subtracting from which, and why? Which is larger, -17 or -164?

Please don't write - -164. A better approach would be to write -(-164)
the same goes for + +. Instead, write simply + or +(164).

Answer 3

oh ok

Answer 4

-17 is a larger number
