Task Analysis

To solve this problem, we need to determine the number of students who received certificates. We are given that 86 students participated in the orienteering competition, 5 students became winners, and the remaining students received certificates for good results.

Solution

To find the number of students who received certificates, we need to subtract the number of winners from the total number of participants and then subtract the result from the total number of participants again.

Let's calculate it step by step:

1. Total number of participants: 86. 2. Number of winners: 5. 3. Number of students who received certificates: Total number of participants - Number of winners = 86 - 5 = 81. 4. Final answer: Number of students who received certificates = 81.

Therefore, 81 students received certificates for good results in the orienteering competition.
