Let's see how good you are at arithmetic. >:-)

What kind of module?

- shubhamsrg

404 ?
(going by a forced logic !) -_-

520 is Opcode guess?

@shubhamsrg @Opcode no

8!!!!

- ParthKohli

That's right! ^

- ParthKohli

Does no one know 4 + 4 = 8?!

- anonymous

for realz

- anonymous

What about 1 + 1, 2 + 2, and 3+3?
Or is it just a trick?

- ParthKohli

@RD⁴² ?

- ParthKohli

What about them?

- anonymous

1 + 1 = 7
2 + 2 = 89
3 + 3 = 228
Why?

- anonymous

I don't get the joke, honestly.

- ParthKohli

I have asked you to just assume that. I didn't ask you to get to a conclusion that 1 + 1 is related to 4 + 4.

- anonymous

It makes no sense, but ok.

Here was my forced logic :
7= (4)(5)/2 -3
89 = (13)(14)/2 -2
228 = (21)(22)/2 -3
So for odd terms like 1+1, or 3+3 , we subtract 3 from n(n+1)/2
for even terms, we subtract 2
now for n, it is 4,13,21 --> So from the differences, I say the next term is 28
hence 4+4 = (28)(29)/2 -2 =404

Sir, you have my respect.

I know this is late, but I object. It's 424.
Let \(\large x + x = \dfrac{1}{2}(57x^2 - 7x - 36)\)
When x = 1, 1 + 1 = 7
When x = 2, 2 + 2 = 89
When x = 3, 3 + 3 = 228
Lastly, when x = 4, 4 + 4 = \(\boxed{424}\)

Looks like it is safe to say that this question is ambiguous.
Sir, you are not supposed to post an ambiguous question, @ParthKohli

- ParthKohli

how is this ambiguous? do you not know 4 + 4 = 8?

- anonymous

Yet, you said 1 + 1 = 7

- ParthKohli

I asked you to suppose 1 + 1 = 7.
I didn't ask you to assume that 4 + 4 will be based on 1 +1, 2 + 2 and 3 + 3.

- anonymous

It does since 2 + 2 = \(\large 8\)9 and 3 + 3 = 22\(\large 8\)
Beside shubhamsrg has other answers. There are several reasonable answers for this, hence ambiguous.

Also, 'suppose' means 'assume,' according to dictionary.

@micahwood50 Thank you!
@ParthKohli He has good points...

- Opcode

It's a trick question :3
We fell for it :P

- anonymous

Oh and don't you know that 1+1 ACTUALLY equal 2?

- anonymous

If 1+1 =7, then it affects numeric system, which can also affect the value of 4.

- anonymous

And we know that 2+2 =89 so if 4+4 = 8 then 2 is bigger than 4.

- anonymous

You have not given whether numeric system affects 4 or not, hence ambiguous.

- anonymous

@ParthKohli

- ParthKohli

If I haven't given so, you shouldn't assume that 4 + 4 is based on the prior sequence.

- anonymous

so you admit this question is ambiguous
