Can You Solve This Intelligence Test? Viral Facebook Puzzle

If 6 + 4 = 210, and 9 + 2 = 711, what is the rule to combine numbers? This "intelligence test" has been shared more than 3 million times on Facebook. On Twitter people claim solving it means you have an IQ of more than 150 (genius level). In this video I ask a question to test if you really understand the rule. As the original test asks, "Share if you understood it."

hey this is precious Roy Walker can you
figure out a pattern in these numbers
this intelligence test has been shared
on Facebook more than 3 million times
it's also gotten popular on twitter with
the tagline that if you understand it
you have a genius IQ of more than a
hundred and fifty points
there are many reasons to question these
claims and perhaps the most startling
part about this intelligence test is
that you never have to prove you
understand the role you can simply
pretend you solved it by sharing the
post or sharing the tweet i often get
people who watch my puzzle videos and
tell me that it was so easy they figured
it out when i asked them what the answer
is
they often tell me a result which is the
trap answer
I think in order to have an intelligence
test
you should always prove that you
understand what's going on in a new
situation so I want to oppose this
problem to you if you understand the
rule you should be able to solve this
problem
give it a try and when you're ready keep
watching the video I'm going to explain
the rule of the intelligence test and
then solve this problem
so when we're looking for a pattern
these numbers we might just start by
adding up the numbers and seeing if
these numbers show up anywhere in fact
it turns out that the sum of the two
digits will be the last two digits or
the last digit our result
now we need to figure out where the
first number or the first two numbers of
our answer come from
well we can do the other operation we
can just subtract the numbers and will
quickly see this is where the first
number or the first two numbers come
from
so we figured out the intelligence rule
we want to add combine two numbers x and
y will take the difference of the two
numbers and then append it to the sum of
the two numbers
so now let's test our knowledge and see
if we can solve a new problem
one way we can interpret this problem is
that we want two numbers to combine so
that the two numbers have a difference
of one and a sum of 23
we have a system of two equations and x
and y if we add up these two equations
we can eliminate the Y variable so we
have 2x equals 24 which we then solve
that x is equal to 12 y will be one less
than that so y equals eleven so we
figured out 12 and 11 combined to be 123
but if we were to truly have an
intelligence as we need to look for all
solutions
there's another way we can interpret our
problem we could have two numbers
combined so that they have a difference
of 12 and a sum of three we can solve
these equations similarly and we'll get
that x is equal to seven and a half and
y is equal to negative 4 and a half
so this is another answer to this new
problem I've suggested i would say this
is a little bit more of an intelligence
test than the original problem and now
i'm going to ask you
share this video if you solve this new
problem
be honest thanks for watching this video
please subscribe to my channel i make
