Thon presents a simple math problem and asks for the result. Margo says it will be several hundred higher than the solution Thon is asking for. Yet Margo is right. Why?

Is this happening in an academic setting? Is Thon a teacher? A student? Is Margo a teacher? A student? Are they at work?

Is the problem an equation? A formula? Does it have one only one right answer? Is it a matter of interpretation? Have circumstances somehow changed so that the correct answer is no longer the correct answer? Is the problem entirely abstract, based on numbers and/or algebraic characters, or does it make reference to real-world phenomena (e.g. currency values, quantities of something, the age/size/attributes of something that isn't constant)?

Is Thon surprised that Margo is correct? Does Margo have some kind of insider knowledge? Is this one of those infuriating Facebook riddles like that one about Monkeys seeing elephants while going to the river?

Thon = HAM? Margo = HTF?

In order to understand: T is asking for a result. Say the result that T is asking for is 16. Margo says it will be of the order of 1000 instead but without knowing the exact solution. Is it correct? Or maybe she knew that it was 1600 already?

Thon presents a simple math problem and asks for the result. --> Can we assume that he asked to a group of people? To a class? Was the solution provided by T before? Did Margo know the solution? Did she only know that it would have been much higher than the one proposed by T?

"it " = the result?

Are units of measurements involved? Relevant the problem statement? Is it about applying a simple math operation? Addition? Subtraction? Division? Multiplication? Others? Did T write the statement? Relevant? Did he make a mistake in writing it? Did T to take into account something? Are the solution and the problem connected to the people he was asking the solution? E.g. "how many pages have the book you are reading?" (maybe not taking into account the books that they had in the backpack). Or maybe he asked to quantify something that the more the better? E.g. "which is the highest number?" and she simply replied "the number that you have in mind but several hundred bigger"

Thon = HAM? Margo = HTF? Assume HAM/HAF

In order to understand: T is asking for a result. Say the result that T is asking for is 16. Margo says it will be of the order of 1000 instead but without knowing the exact solution. Is it correct? Not quite. Margo knew the solution, and the result was less than 1000 Or maybe she knew that it was 1600 already?

Thon presents a simple math problem and asks for the result. --> Can we assume that he asked to a group of people? Yes To a class? Yes Was the solution provided by T before? No Did Margo know the solution? Yes Did she only know that it would have been much higher than the one proposed by T? FA

10

+3

+143

And then start working vertically, with numbers ending up in higher places than they should?

Margo says it will be several hundred higher than the solution Thon is asking for. --> so I have a FA here. I am assuming that Margo knows the answer and knows also what will be the answer given by Thon right? Is the solution Thon is asking for wrong? Wrong in absolute terms or wrong given its typo? Or maybe right given the typo but wrong in absolute terms?

Are distances involved? Real world data? E.g. distance earth-moon? Is being "several hundred higher", a huge difference with respect to the solution asked by Thon?

Are decimal places relevant? Are numbers to be added? is finance involved? Money? Something continuously updating? is time involved? Is the solution proposed by Thon obsolete (e.g. referred to a date previous than 2020)? Is COVID relevant?

Is the typo: in a math operation? In an "English written" part?

Oh is it something in different notations among USA and UE relevant? E.g. in UE people do not use the .n notation for decimals, rather the comma notation which I think it's used for separating thousands in US. So basically writing 7.4 in UE it's like writing 7400, while 7,4 in UE is 7.4 in US. Something like this involved?

Did T made a mistake in writing a math symbol (number? operation sign? equal sign? addition?)? Did he multiply rather than adding? Did T took the statement of the problem relevantly from somewhere else? e.g. a textbook? on the internet? Did T make a mistake in the statement of the problem? In an hint given? While writing down the solution? Relevant?

Units of measure relevant? Did T misstate the magnitude of something (e.g. meaning "mm" but writing "cm")? Or confuse metric with imperial units? Use a unit that are ambiguous (e.g. "ounce" or "pound")?

I'm still somewhat confused so let me see if I have it right: Is the answer Thon is looking for correct given the typo? Incorrect? Is Margo's answer correct given the typo? Incorrect?

Is the problem printed out? presented on screen? relevant?

You said that Margo has insider knowledge. Do any of the other students have the same insider knowledge?

To clear up the FA: Is there an answer/solution to the problem? Is the one of Thon a typo? can the answer to the problem be defined as "correct" or "wrong"? Did Margo give the solution? Is Thon the math professor? Is neither solution correct given the typo?

Its there a dialog in the statement of the problem? Is the symbol "!" relevant? (i.e. factorial) Does the typo involve a symbol that can be found in normal keyboards? Is it any of these: ". , - : ; _ * ] [ ( ) / & % = ^" ? Are percentages relevant?

No, the solution he's asking for is right --> does it coincide with the one that Margo gave?

Is it a multiple choice question? An open question? A question to be completed? Are three dots relevant? If so: relevant because they let people know that something goes to infinity while it is not? That an answer is to be completed? Than a number is periodical while it is not? That a figure is a line while it is a segment? That there is a series of numbers multiplied?

We said that the problem asked to do a sum right? Is it about summing the same number n times (which is equivalent to multiply it n times?)? To sum different numbers? sum apples with oranges? Use the summation sign?

The answer to the problem is correct Did Margo give the solution? No! Is Thon the math professor? No Is neither solution correct given the typo? No, Thon's solution would have been correct

Its there a dialog in the statement of the problem? Not sure what you mean by "dialog" - do you mean "is it a word problem"? If so, No Is the symbol "!" relevant? (i.e. factorial) No Does the typo involve a symbol that can be found in normal keyboards? Yes Is it any of these: ". , - : ; _ * ] [ ( ) / & % = ^" ? Yes, it's a semicolon Are percentages relevant? No

No, the solution he's asking for is right --> does it coincide with the one that Margo gave? No

The specific sum, which is not particularly relevant, is "add the whole numbers from 1 through 5" sum apples with oranges? Use the summation sign?

So the intended problem is to "add the whole numbers from 1 through 5", i.e. 1+2+3+4+5=15 ? However, Thon makes a typo, that makes it ask for the result of a completely different calculation? If so, does the typo change the operation of addition to multiplication (i.e. to 1*2*3*4*5)? make it involve whole numbers that can be written using the digits 1-5, but with more than one digit per number (e.g. something like 11 + 12 + 13 +... + 45 + 55)? Change from "whole numbers" (as in integers) to some other set of numbers?

Is the problem written as 'add the whole numbers from 1 to 5'? '1 + 2 + 3 + 4 + 5 ='?

So the typo involved a semicolon? Did Thon add a semicolon somewhere be didn't mean to? Omit a semicolon somewhere it was supposed to be? Is programing relevant? Was Thon writing a program to add up numbers?

Relevant what language he was using? Did the missing semicolon cause the program to loop for longer than it should? Make it do something other than addition? Interpret the input differently (e.g as 12345 instead of the individual numbers)?

****SPOILER****

Thon, a programming teacher, wrote a simple program to sum the numbers from 1 through 5 and asked his class for the result; Margo said "500." Since Thon omitted a semicolon from the program, when he executed it, the result was "500 Server Error."

(Their names were clues: "Thon" is part of the programming language "Python," while "Margo" came from "programmer" spelled backward.)

Well done!
