Hello, the problem of mathematical clock is easy to do, as long as you master the following basic knowledge:

1, the second hand walks the big grid for 5 seconds, and the angle is 30;

2. The minute hand walks a big grid for 5 minutes, and the angle is also 30;

3. Walk clockwise for one hour at an angle of 30;

4, the hour hand walks one grid, and the minute hand walks one circle, which is 360; The second hand goes 60 times.

The general mathematical clock problem starts from these aspects. As long as you master it, it should be no big problem!

I hope it helps you!
