Problem Analysis

In a orienteering competition, 86 schoolchildren participated. The winners were 5 people, and the rest of the children received certificates for good results. We need to determine how many children received certificates.

Solution

To find the number of children who received certificates, we need to subtract the number of winners from the total number of participants.

Let's calculate it step by step:

1. Total number of participants: 86. 2. Number of winners: 5. 3. Number of children who received certificates = Total number of participants - Number of winners.

Let's calculate it:

Number of children who received certificates = 86 - 5 = 81.

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