"Ugh, It's been so hot out lately, why does it have to be $32$ ~32~ degrees…"
" $32$ ~32~ degrees? That's freezing!"

You've had quite enough of confusing conversations with Americans who assume you're using Fahrenheit when Celsius is clearly the way to go. Rather than argue with them, you've settled for writing a program to conveniently convert temperatures measured in degrees Celsius to Fahrenheit instead.

You came across the following formula, which holds true given that $F$ ~F~ is a temperature in degrees Fahrenheit while $C$ ~C~ is that same temperature in degrees Celsius:

$\displaystyle C = \frac 5 9 \times (F - 32)$

Given a value of $C$ ~C~, which is an integer between $-40$ ~-40~ and $40$ ~40~ (inclusive), determine the corresponding value of $F$ ~F~, so that you can express the equivalent temperature in degrees Fahrenheit for the Americans' benefit.

It's guaranteed that $C$ ~C~ will be chosen such that $F$ ~F~ will come out to exactly an integer, but you may output it with $0$ ~0~ or more digits after the decimal point.

Input Specification

The first and only line of input consists of a single integer, $C$ ~C~.

Output Specification

Output a single integer, the temperature in degrees Fahrenheit which is equivalent to $C$ ~C~ degrees Celsius.

I feel a lot better knowing other people also struggle with basic math, lol

That was a nice problem.

$F = \frac{9}{5} C + 32$ ~F = \frac{9}{5} C + 32~

It worked for me with this formula:

F = (C*1.8)+32

Although quite simple, this is the first code that I write alone and it works

Dont have to do all the MATH on your own, thats what the program you create is for. BUT Keep in mind, You need to remember Math Formulas and Methods to Isolate the Unknown Variable. Im not giving Code, so hopefully this isn't giving too much help. Get F alone in the Above formula.

C = 5/9 x (F - 32)

C / 5/9 = (F - 32)

C / 5/9 + 32 = F

Hope this directs some of ya a little.

This took me a good minute, had to dig deep in the Math memory from School.

the formula was not easy to figure out until i googled it.
