## Usage

Basic Arithmetic:

2 + 2 * 2 = 6

(2 + 2) * 2 = 8

573/2 - 1221*6 = -7039.5

Power and Logarithms:

3 ^ 2 = 9

*(3 to the 2nd power)*sqrt(9) = 3

9 ^ 0.5 = 3

log(2.7183) = 1.00000668491

*(natural logarithm base-E)*log10(2.7183) = 0.434297385125

*(logarithm base-10)*log10(100) = 2

Trigonometric Functions:

sin(90) = 1

arcsin(1) = 90

*(you may also use asin instead of arcsin)*cos(60) = 0.5

arccos(0.5) = 60 <

*(you may also use acos instead of arccos)*tan(45) = 1

arctan(1) = 45

*(you may also use atan instead of arctan)*
