Give the step-by-step reasoning process and then the final answer. A man used to have 39 cows but last year 25 of them died and he sold 6 of them. This year the number of the cows increased by 24 and the man bought 43 more. His friend gave him 8 cows as a gift. How many cows does the man have now?
Last year he had 39 cows - 25 cows - 6 cows = 8 cows. This year after the number of the cows has increased he has 8 cows + 24 cows = 32 cows. After he bought more cows he now has 32 cows + 43 cows = 75 cows. After his friend gave him cows he now has 75 cows + 8 cows = 83 cows.
The final answer: 83.
