1. Share and share: If there are four children, but three of them want to share three apples, how many apples can each child get? The answer is 1. Because there are four children, and each child gets an apple, the number of apples left is 4-3= 1.
2. Simple quantitative relationship: If there are four balloons, but three are blown away by the wind, how many balloons are left? The answer is 1. Because there were 4 balloons and 3 were lost, the number of balloons left was 4-3= 1.
3. Simple math problem: If there are 4 pieces of candy, but you ate 3 pieces, how many pieces do you have left? The answer is also 1. Because there are always 4 pieces of sugar, and you ate 3 pieces, the remaining amount of sugar is 4-3= 1.
The importance of solving problems:

2. Solving problems can help us understand the world better. By solving the problem, we can understand the essence and complexity of the problem more deeply.
