You can put this solution on YOUR website! Since "a football team gains 7 yards", this means that they have +7 yards
Now because the team "loses 26 yards", this then means that have 26 yards taken away which is represented by -26. So we now have +7-26
In the end, the team "gains 40 yards" which is written +40. Add this to the last expression to get +7-26+40
So we now have the expression +7-26+40. Rearrange the terms to get +40+7-26. Add +40 and +7 to get +47.
So we now have +47-26
Subtract to get +21
So this means that they've gained 21 yards
