1 degree = 60 minutes? 1 minute = 60 seconds
Angle is the unit used to measure angles, and its symbol is "°". An angle is divided into 360 equal parts, each part is defined as 1 degree (1°).
In the angle system, 1°=60′, 1′=60″, 1′=(1/60)°, 1″=(1/60)′.
The angle system is an example of using base 60.

In the angle system, 1°=60′, 1′=60″, 1′=(1/60)°, 1″=(1/60 )′.
The angle system is an example of using base 60.
2 Arithmetic Rules
When adding two angles, ° and ° are added, ′ and ′ are added, "and" are added, and if it reaches 60, 1 is added.
When subtracting two angles, ° is subtracted from °, ′ is subtracted from ′, and " is subtracted from ". If it is not enough, 1 is subtracted from the previous unit and regarded as 60.
Definition of 3-digit system
The system that uses degrees (°), minutes (′), and seconds (″) to measure angles is called the angle system.
Angle system: An angle that stipulates that 1/360 of a circumferential angle is 1 degree. The unit system that uses degrees as the unit to measure angles is called the angle system.

Operation Rules
When adding two angles, ° and ° are added, ′ and ′ are added, "and" are added, and if it reaches 60, 1 is added.
When subtracting two angles, ° is subtracted from °, ′ is subtracted from ′, and " is subtracted from ". If it is not enough, the previous unit is reduced by 1 as 60.
