A soccer game is 90 minutes with m minutes of stoppage time. The total time is 90 + m. How long is the game with 23 minutes stoppage time?

The total time is 90 + m = 90 + 23 = <<90+23=113>>113 minutes. Answer: \boxed{113}.

To find the total time of the game with 23 minutes of stoppage time, we add the 90 minutes of regular play time to the stoppage time.

90 minutes + 23 minutes = 113 minutes

Therefore, the game is 113 minutes long with 23 minutes of stoppage time.

To determine the total length of the game with 23 minutes of stoppage time, you need to add the 90 minutes of regular game time with the additional minutes of stoppage time. So, the total time can be calculated as follows:

Total Time = Regular Game Time + Stoppage Time

Substituting the given values:

Total Time = 90 minutes + 23 minutes

Now, you can simply add the values to find the answer:

Total Time = 113 minutes

Therefore, the game would be 113 minutes long with 23 minutes of stoppage time.
