# Devil’s Calculator – A Math Puzzle Game (Level 8 to 15)

hello guys how are you doing today I
will solve level eight to level 15 in Devil’s calculator a math puzzle game
have already made a video on solving level 1 to 7 in devil’s calculator so
you can go and check it out so let’s get started this is how the application
looks like we are currently on level 8 if you haven’t seen my first video on
devil’s calculator go was that first in that I have explained about the devil’s
calculator and how to solve puzzles here this is the in out button we will give
input to it and it gives output we want the output to be triple 6 which is the
devil’s number so let’s solve the level 8 we will use the same technique which
we use to solve level 1 to 7 let’s see here we will give input as 0 then in our
function it’s giving minus 3 we give input 1 in our function it’s giving
minus 2 if we give 2 input function that’s giving minus 1 3 in our function
it’s giving 0 so what’s the logic behind like I’m straightened out if I use 4 in
out function its giving 1 7 cannot function it’s giving full small so maybe
it’s subtracting mine subtracting 3 so let’s try if we use 6 6 9 in our
function it’s giving double 3 6 so what’s the logic behind this if we
use headers in our function then it’s giving minus 2 double 3 how about if we
use 800 in our function it’s giving 5 double 3 if we use triple say you know
function it’s giving triple 3 so I’m still not getting okay okay so I got the
logic if we use 8 8 8 it should be giving triple 5 here so if we use in our
function it’s giving triple five so it’s subtracting 3 from each desert so if we
use 3 in our function it will subtract 3 from 3 which will give 0 if we use 777
of 4 times 7 in our function it will give 4 times 4 so we will use triple 9
in our function so subtracting 3 from each desert so it will give 4 6
boom we are on level number 9 now so let’s see
same technique vo in our function it’s giving 0 1 in our function it’s giving –
82 2 in our function it’s giving – 6 3 in our function it’s giving – 80 so we
can’t use food it’s burning I have already explained in the video first
like we can’t use the burning number so in this decimal is burning for is
burning and 8 is burning so we are left with 0 1 2 3 5 6 7 9 so we can use this
numbers as only if we use 1000 in our function it’s giving – 3000 so I’m still
not getting the logic so we use triple a malfunction it’s giving -1 double nine
eight so okay so it’s multiplying with minus 3 multiplying the number with
minus three so if we use triple 2 hill and we use then our function will give
minus triple six because it multiplying with minus three caught the logic so –
triple 6 is there so we should use first we’ll clear this then we will use minus
2 you know function boom triple 6 now we are on level number 10 so let’s write
this 0 in our function it’s giving – seventeen point five times seven eight
oh my god so let’s try this with one in our function – seventeen point five
times two three so I’m not getting the logic – in our function it’s giving –
sixteen point five times six over oh my god so let’s try with some bigger number
like 1000 in our function it’s giving five three seven point four times seven
eight so we are getting closer so if we use teen hundred in our
function it’s giving eight fifteen so it must be between thousand and fifteen
hundred so that’s why with one two five zero in our function oh we have close
six seven six point four times six seven I’m not getting the logic so let’s try
with hit and trial method so it should be lesser than 1 – 5 0 so it let me try
with one two three zero and out function Oh
boom we’re very close so let’s try with one two three one you know
function so it must be between 1 2 3 0 and 1 2 3 1 so let’s try with the
decimal numbers 1 2 3 0 point I will use 6 in our function is equal to 6 6 5
point 4 times 8 9 so it should be 1 2 3 let me clear this 1 2 3 0 point 8 if we
use let’s see this if we will try echoing able to get the logic so if we
go triple six eight in trial method works fine so I should I’m confused like
how I solve this but to hit and trial method is more successful so they have
it no we are on level number 11 so who we will solve this so we will use the
same logic which is 0 in our function it’s giving minus y1 in our function it
will give minus 4 2 in our function it’s giving minus 3 3 in out function it’s
giving -2 maybe it will it is subtracting minus 5 with this try with
bigger numbers like if we use that’s why with 5 5 5 so if we use you know
function it’s giving 0 so the same logic like if we use
triple 9 it should give triple for so it’s subtracting 5 with each digit so if
we need to get triple 6 here so what we should use so let me try this way if we
use triple 9 it’s giving triple 4 so how to you’d with triple six if we use the
inner function it’s giving triple 1 so how about if we use some minus symbols
here so if we use they not function oh my god it’s giving – triple sex so
here’s something so if let me clear this and use minus 1 1 1 in our function it’s
given – triple six okay I got the logic so if we use triple one so first it will
minus one from five so it will be minus X again minus six in the second is it –
six in the last year it so all will be plus so we are getting boom so this is
getting confused so if we use dropper one in our function
if we use – again some – confused with this if we try with one one okay so
let’s try this if we use one one one in our function – and if we type this it’s
giving – triple six so if we try with – in our function 1 1 1 – and how to put –
let me clear this if we use – in our function – ok so now the thing is that we are
putting the – then in our function – and triple 1 so if we go to the equivalent
boom we got the triple 6 here so now we are on level number 12 so
let’s try this we will see 0 in our function is equal to 0 1 in our function
it’s giving – 80 – 3 in our function it’s giving – 85 in our function is
giving – 78 we have decimal two four eight which are
burning we can’t use this so I have got the logic like if we use
5 so it’s subtracting minus 83 with this so we got minus 78 so when we use nine
and out function and it should give minus 74 so it’s subtracting minus 83
with the number so if we use 973 so it should give 890 you know function it’s
giving 890 so let’s try with if we use 6 in our function so oh that’s a
difference so if in case of the old numbers its subtracting with the – 83 so
if we use the even numbers so it’s a it’s multiplying with minus 3 so if we
use something like 6 0 0 so it will give minus 1800 so in our function it’s give
minus 1800 so we need to produce triple 6 here so what should be given so if we
use – triple – my bird we can’t use 2 here so how to get triple – so triple 2
plus 83 so it should be 3 0 5 so we can leverage 3:05 here so if we use in our
function – 3 0 5 so if we use this mine how like if we use this kind of
something so let’s try again so if we use you know function – now function 3 0
5 – so get triple shakes boom baba Kazami so
it’s giving some advertisement and we will click on the later button so let’s
start with levels number 13 so in this zero and one is burning so we can’t use
zero and one so we will try with two in our function it’s giving ten four in our
function it’s giving 14 so when we tried with the two it’s giving four three a
ten when we tried with four it’s giving fourteen
so let’s write with sex in our function it’s giving eighteen so what is the
logic behind this it’s multiplying with two and adding six in it so if we use
eight and our function multiplying it by 2 is 16 plus 6 it will give 22 so we
will try with 3 3 0 so it will give multiply with the two it will give 6 6 0
plus 6 it will get triple 6 but we can’t use 0 in here so how to go about this
thing so if we use something like how what should we use so if we use 72
already clear this so if we use 7 T 2 and our function it’s
giving 150 so let’s try with 72 2 times it’s giving 3:06 we are getting closer
if we use 72 3 times in our function it’s giving 6 18 so is where we are very
close to the solution so if we use 76 3 times in our function its 6:50 let’s
write with 77 3 times in our function so it
6:58 so let’s try with 78 three times in our function so 78 into two plus six
then the answer will be in two two plus six then the answer will be in two two
plus six so we should get triple six a boom now now we are on the level 14 so
let’s try the same procedure zero in our function is doing zero 1 in our function
if given 1 2 in our function is giving two three you know function is giving
three oh really like seriously so if we try the triple
sec you know function so it’s some different logic is there so triple six
is giving one two three two okay so if we use 100 you know function it’s giving
144 what’s the logic behind this if we you too hindered you know function and
it’s giving 310 so if we use to hinder two times in our function it’s giving
four double six if we use 300 times you know function it’s giving 7:06 so if you
use do it eight two times in our function it’s giving 670 so we need to
try with some other logic if we use 400 in our function it’s giving 620 if we
use 436 you know function it’s giving 664
so if we use function boom we tried with the hittin trial and it worked so the
answer was for it 38 so now we are on the level 15 that’s all this oh my god
oh my god so the number two three four five six seven eight nine and decimal is
burning only with God with zero and one so if we click on dear
in our function it is giving 0 1 in our function it’s giving one so maybe maybe
thing is that it’s using binary digits so if we use 1 0 in binary it’s 1 0 if
we convert this in the decimal so it should give – yeah it’s giving 2 so if
we use 1 1 it should give 3 in terms of decimals ok so if we use triple 1 it
should give 5 oh sorry it’s giving 7 so it’s a concept of binary digits so for
getting the triple 6 the binary digit deserts are 1 0 1 0 0 1 1 0 1 0 so this
will give triple 6 I I have tried this with another application so to convert
the triple 6 into binary digits so we have 1 0 1 double 0 1 1 0 1 0 so if we
use the in our function booms we got to triple 6 so I have sold till 15 hope you
like this video do give it a thumbs up thanks for watching and bye bye
