A football team gained 4 yd, lost 2 yd, gained 11yd, lost 8 yd, and then lost 9 yd. Find the net gain or loss.

4 + 11 = 15 yards gained
2 + 8 + 9 = 19 yards lost
15  19 = ? 
so the 15  9=4 okay thanks ms. sue for helping me with my 7th grade pre algebra hw I will probably need more help I will jut post my other questions too.

You're welcome.
Note that that's 4 yards lost. 
and then like um my next question is maria had $123 she spent $35,loaned $20 to a friend and received her $90 paycheck how much does she have now? so you would do 123 20=103
and then 103  20=83
and 83 + 90 =wich is 173 so that would be the answer right?
