 On the ground in front of an apartment building **tiles need to be placed**. The ground has a **square shape with a side of N meters**. The tiles are **"W" meters wide** and **"L" meters long**. There is one bench on the ground with a **width of "M" meters and a length of "O" meters**. There is no need to place tiles under it. Each tile is replaced for **0.2 minutes**.

-We see that the **number of bitcoins** and **the number of Chinese yuans** will be given in the input. The **output** should be in euro. The exchange rates that we have to work with are specified in the task. We notice that we can only exchange the sum in BGN to EUR, therefore, we **first have to calculate the whole sum** that Pesho has in BGN, and then **calculate the output**.

 As we have information for the exchange rate of Bitcoins to BGN, we can directly exchange them. On the other hand, to get the value of **Chinese yuans in BGN**, first, we have to **exchange them in USD**, and then the **USD to BGN**. Finally, we will **sum the two values** and calculate how much euro that is.

-We could write an expression that calculates the annual income without brackets as well. As multiplication is an operation that has a higher priority over addition, it will be performed first. Despite that, **writing brackets is recommended when using more operators**, as this way the code is **easily readable** and chances of making a mistake are smaller.
