"Powershell" "math class" directly calls the. Net method of the math class for numeric operations

The calculation of numbers in Powershell we are often used to simply use arithmetic notation, but for relatively complex numeric operations we need relatively complex functions or commands, and here we introduce a method of computing directly through.
