Cowboy Chris rounded up the cattle from the range and herded them into the corral. He forgot to close the exit chute, though, so the cattle just ran out the other end. By the time he realized his mistake and closed the chute, he only had 413 cattle left. His son (who had just learned to count and didn't realize the cattle leaving was a problem) had counted 158 cattle as they were running out of the corral. How many cattle had Chris rounded up?
