Theres a reason why kids can solve this in less than 5 minutes. I did it in 30 seconds. I dont know how any of you were taught to logically solve problems early but I defnitely saw something like this on IQ tests. This is simply about pattern recognition. The reason why young kids can get this so fast is because its one of the only few forms of math they know at that age. From this list you can automatically determine that every digit has a place value like binary but this would be something else..im having a brainfart at the moment. Anyway so you can already take all the numbers that equal 0 and assign them all values of 0. So now we have 1=0 2=0 3=0 5=0 7=0 and now we can take another number and figure out its value. so let me try to type it out properly with the value above the number. Keep in mind our goal is to figure out 2851. right now we have 0+0+?+0=? 2 5 8 1=? Now we see that 0000=4 and 9999=4 so we can say that 0 and 9=1 Now our list looks as follows: 0=1 1=0 2=0 3=0 4=? 5=0 6=? 7=0 8=? 9=1 So now we only need 8's value to solve this problem. 8193=3 now expand it. ?+0+1+0=3 8=2 Im sorry but im not going to white this out. if people are smart enough theyd already know the answer before coming here
