How to do basic mathematical computations (in Julia)

Task

How do we write the most common mathematical operations in a given piece of software? For example, how do we write multiplication, or exponentiation, or logarithms, in Python vs. R vs. Excel, and so on?

Solution

Mathematical notation	Julia code
$x + y$	`x+y`
$x - y$	`x-y`
$x y$	`x*y`
$\frac{x}{y}$	`x/y` (or `y\x`)
$⌊ \frac{x}{y} ⌋$	`x÷y`
remainder of $x \div y$	`x%y`
$x^{y}$	`x^y`
$\| x \|$	`abs(x)`
$\ln x$	`log(x)`
$\log_{a} b$	`log(a,b)`
$e^{x}$	`exp(x)`
$π$	`pi`
$\sin x$	`sin(x)`
$\sin^{- 1} x$	`asin(x)`
$\sqrt{x}$	`sqrt(x)`

Other trigonometric functions are also available besides just sin including cos, tan, etc.
