                  + $51.22

withdrew:  - $5.23

                 -  $10.22

                  - $7.89

Answer:      -  $10.22 ,   - $7.89 , - $5.23 , + $34.98, + $51.02,  + $51.22

Negative numbers are always less than positive numbers. The largest negative numbers are the lowest values.

Answer:

Beginning balance: $128

Deposited: + $34.98 + $51.02 + $51.22  = + $137.22
