a football team gained 12 yards on one play, lost 40 yards on another and gained 34 yards on the last play of the first half. they had already gained 345 yards during the half. what was the total yardage gain for the first half?

The answer is 351

345 + 12 + 34 - 40 = ?

To calculate the total yardage gain for the first half, you need to add up the yardage gained on each play.

1. The team gained 12 yards on the first play.
2. They lost 40 yards on the second play.
3. They gained 34 yards on the last play of the first half.

To find the total yardage gain, add these individual gains and losses together:

12 yards + (-40) yards + 34 yards = 6 yards.

The total yardage gain for the first half is 6 yards.

However, you mentioned that the team had already gained 345 yards during the half. If you want to calculate the total yardage gained by the team so far, you would add the yardage gained on each play to the already gained yardage:

345 yards + 12 yards + (-40) yards + 34 yards = 351 yards.

The total yardage gained for the first half is 351 yards.

To find the total yardage gain for the first half, you need to add up the yardage gained on each play.

First, let's start with the yardage gained in the first play, which was 12 yards.

Next, we need to subtract the yardage lost in the second play, which was 40 yards.

Then, we add the yardage gained in the last play of the first half, which was 34 yards.

Finally, we add the total yardage gained during the half, which is already given as 345 yards.

Let's do the math:

12 yards (first play) - 40 yards (second play) + 34 yards (last play) + 345 yards (total yardage already gained) = Total yardage gain for the first half

12 - 40 + 34 + 345 = Total yardage gain for the first half

-26 + 34 + 345 = Total yardage gain for the first half

58 + 345 = Total yardage gain for the first half

403 = Total yardage gain for the first half

So, the total yardage gain for the first half is 403 yards.
