so, i was siting on the bus hearing this song: Youtube link

thinking about what i can write for first article. i am sure there are many students here that hate math and dont understand how it will help tham with real life problam, so here is one option how to use it.

Mission #63: Deal 150 000 dmg in 1 round
Task: Deal 150 000 damage in one battle round today

Rewards:

5.00 Gold


so, i want to see if it worth to do 150 dmg to get 5 Gold
, since i will probably waste wep/gift/food that will cost some.

so first we writh:
less than 5Gold
prodects cost need to make more than 150Kdmg



and second:
5Gold
>how much i waste

it wil be an equation of :
W-Q1wep, F-Q5food , G-Q5gift
p.w-will be the price of wep , p.f-price of food and p.g-price of gift
the > is becuse we want to use less than 5 gold to do so

so if u see: F*(p.f) its the amount u paid on food , F-will be the number of food used, and p.f the price it cost u , and same methood for the rest.

so:
5Gold
>F*(p.f)+G*(p.g)+W*(p.w)

but as we know , prices of gift will alweys be almost duble than food , so we willl never use gift unless we cant use food anymore:

if:
10>F than we use: 5Gold
>F*(p.f)+W*(p.w)
but if we need more:
F>10 than: 5Gold
>10*(p.f)+G*(p.g)+W(p.w)


with spliting the equation we mange to get rid of one unknown variable so it make it easyier to keep going:

my geuss is that prices are too high so it will not get to useing the secound part, so let me keep going only on the first equation :

5Gold
>F*(p.f)+W*(p.w)


now, what can we know about the conniction between F(food) and W(weapons)?

every food bring u 5 hits and let u use 5 weap: W=5F (it is easyier to get to 150K dmg with weap since it make duble dmg))
so lets replace the W with 5F so we get rid of anouter varible:
5Gold
>F*(p.f)+(5F)*(p.w)

we will use common denominator (מכנה משותף חברים , check the wiki and replace to your lenguge )

5Gold
>(F)*[(p.f)+5*(p.w)]

5Gold
>(F)*[(p.f)+5*(p.w)]


now we check prices on market, i use DenizGezmis great eth-trade article but u can use any price u get:
(p.f)=0.45Gold
(p.w)=0.08Gold


5Gold
>(F)*[(p.f)+(5)*(p.w)]

5Gold
>(F)*[(0.45Gold
)+(5)*(0.08Gold
])]

alweys start from the inside out and multiplication before adding:
5Gold
>(F)*[0.45Gold
)+(0.4Gold
])]

5Gold
>(F)*[0.85Gold
]

divading:
5Gold
/[0.85Gold
]>(F)*[0.85Gold
]/[0.85Gold
]

5.88Gold
>F

what the meining of this? our prices limit us to use less than 5.88 food to make it profible!
lets try puting 5 food and than using 6 food for seeing our cost:
remember! for every food we are using we will use 5 weap, and we cant use half food or weap!

using 5 food:
5Gold
>5*0.45Gold
+(5*5)*0.08Gold

5Gold
>1.98+2=3.98
well if we use 5 food and 25 weap it will be proftible

using 6 food:
5Gold
>6*0.45Gold
+(6*5)*0.08Gold

5Gold
>5.1
the sentence is false since it cost more than what we profit!

ok so we finish the cost side, now lets see the dmg side:

150K dmg> cost

150kdmg>3.98 using: 5 food and 25 weap:

use the calc

becuse every player have diffrent set u need to use it yourself , click on "load my data"
than change the inpute of food limit= (5) gift limit= (0) and Weapon quality =(Q1)
click calculate

did it make to 150K dmg? if not, its not worth to waste that gold

u can use it to see if the B.H worth it too, but if u do, u shold chose how much dmg do u need from begining

if u r still here i give u a virtual B.H. madel


if u find any mistake or my sanity make a comment below!
plz vote and sub

About the game:


USA as a world power? In E-Sim it is possible!

In E-Sim we have a huge, living world, which is a mirror copy of the Earth. Well, maybe not completely mirrored, because the balance of power in this virtual world looks a bit different than in real life. In E-Sim, USA does not have to be a world superpower, It can be efficiently managed as a much smaller country that has entrepreneurial citizens that support it's foundation. Everything depends on the players themselves and how they decide to shape the political map of the game.

Work for the good of your country and see it rise to an empire.

Activities in this game are divided into several modules. First is the economy as a citizen in a country of your choice you must work to earn money, which you will get to spend for example, on food or purchase of weapons which are critical for your progress as a fighter. You will work in either private companies which are owned by players or government companies which are owned by the state. After progressing in the game you will finally get the opportunity to set up your own business and hire other players. If it prospers, we can even change it into a joint-stock company and enter the stock market and get even more money in this way.


In E-Sim, international wars are nothing out of the ordinary.

"E-Sim is one of the most unique browser games out there"

Become an influential politician.

The second module is a politics. Just like in real life politics in E-Sim are an extremely powerful tool that can be used for your own purposes. From time to time there are elections in the game in which you will not only vote, but also have the ability to run for the head of the party you're in. You can also apply for congress, where once elected you will be given the right to vote on laws proposed by your fellow congress members or your president and propose laws yourself. Voting on laws is important for your country as it can shape the lives of those around you. You can also try to become the head of a given party, and even take part in presidential elections and decide on the shape of the foreign policy of a given state (for example, who to declare war on). Career in politics is obviously not easy and in order to succeed in it, you have to have a good plan and compete for the votes of voters.


You can go bankrupt or become a rich man while playing the stock market.

The international war.

The last and probably the most important module is military. In E-Sim, countries are constantly fighting each other for control over territories which in return grant them access to more valuable raw materials. For this purpose, they form alliances, they fight international wars, but they also have to deal with, for example, uprisings in conquered countries or civil wars, which may explode on their territory. You can also take part in these clashes, although you are also given the opportunity to lead a life as a pacifist who focuses on other activities in the game (for example, running a successful newspaper or selling products).


At the auction you can sell or buy your dream inventory.

E-Sim is a unique browser game. It's creators ensured realistic representation of the mechanisms present in the real world and gave all power to the players who shape the image of the virtual Earth according to their own. So come and join them and help your country achieve its full potential.
