Rhonda decided to keep a record of her weight gains and losses over six month period. The results are as follows:
Mouth 1  +2 lbs
Month 2  1 lb
Month 3  3 lbs
Month 4  +1 lb
Mouth 5  4 lbs
Mouth 6  +3 lbs
How much was the total change in Rhonda's weight for this six month period?
PLEASE help me!!!!

2 + 1 + 3 = 6
1 + 3 + 4 = 8
8  6 = 2 pounds lost
