Solve if u r a genius ! 11 x 11 = 4 ; 22 x 22 = 16; 33 x 33 = ???
Not yet, don't want to influence anyone with wrong info.
I see where you're coming from, and how you got that, but I'm going to say 36.
This is more of a teaser (unlike the problem he gave us using all 4's which is a straightforward calculation) and there's ways to interpret it. I'm assuming that the "X" between the numbers may be taken to mean multiplication. If, however, it means something else, then another solution is possible.
That said, don't expect Classik to ever give an answer but rather foster debates from everyone. I will show my work once others had a chance to give their input, then you will see I have a logical reason (and not a guess) why I stated what I did. And to give some tantalizing examples, I claim that
121 x 3 = 12
605 X 5 = 100 by extrapolating out the information given.
Using your logic I get 484 x 4 = 64
36, like Tim said.
hm, 605 x 5 would be 55 in my understanding
I'm no good at math.
Not for the past 20 years, at any rate. I might have been better once, when my head was clearer.
I've never been good at anything beyond basic math....but I love numbers.
You are correct. You caught on fine. Good job.
Let me give another hint besides thinking in area. Take the product of the numbers and that both Classik and I gave, and divide by the "answer". What happens?
I have no idea what "think area" means.... I've never done math in English. :-(
I just added + signs at a certain point and all equations were right, except your second one and deborah's.
Maybe I'm not as genius as you are.
Thank you, sir. You gave great hints.
It's the same number for all of them. I tried to find out what is special about 30.25 but couldn't find anything.
I used all multiplication but division is just the inverse of multiplication.
Yhea I figured out what you guys were doing but I don't get the significance of 30.25
Neither do I. Maybe it's not so important that it's 30.25, but rather that it is a constant number...?
Anyway. My solution seems to be easier and works with Classik's original post. And the more uncomplicated solution is always the better one.
I come up with 36 too... looking at this as a logic puzzle rather than a math puzzle.
(11 x 11)= 4 can be written as (1 + 1) x (1 +1) = 4 same as 2 x 2 = 4
Following the same pattern,
22 x 22 = 16 same as 4 x 4 = 16
33 x 33 = 36 same as 6 x 6 = 36.
Can extrapolate this out to:
44 x 44 = 64
55 x 55 = 100
66 x 66 = 144
Separate names with a comma.
