A calculator is a tool that performs mathematical calculations. It allows users to perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
The Clock utility consists of a UTC (Coordinated Universal Time) and local time clock, as well as a stopwatch. The UTC clock displays the current time in the UTC time zone, which is commonly used as a global time reference. The local time clock displays the current time based on the user's local time zone. The stopwatch feature allows users to measure elapsed time accurately.
The Ο utility allows you to calculate the value of Ο (pi). Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is an irrational number, approximately equal to 3.14159. The Ο utility provides a convenient way to calculate Ο and perform related calculations involving circles and trigonometry.
