Item #:####
Object Class: Keter
Special Containment Procedures: Due to SCP-####'s anomalous effects, SCP-#### is to be handled by C-class personnel higher that have been granted access by Founder researchers with level four or higher. Currently SCP-#### is kept in a one meter by one meter by one meter solid glass case at Site-eleven.
During SCP-####'s containment, all staff are reminded to not make or take any phone call around SCP-#### since it will trigger SCP-####'s effect. Any staff that disobeyed this reminder twice will be noticed on one of SCP-####'s page entry and will be [DATA EXPUNGED] by the O5 Council Member
Description: SCP-#### is a fifteen cm by twenty-three cm children's number book by an unknown author. SCP-#### appears to have one hundred twenty eight pages based on the outside appearance with most of them are blank except for the first five pages that consists the picture all the non-negative integer from zero to nine.
Any mathematical number symbol written/typed about SCP-#### will result in the writer suddenly forget any crucial information what the writer intend to write/type next in the first place. The number that the writer wrote for example twelve (using symbol) automatically makes the writer forget that information for the next twelve hours before the writer can remember what the original information was.
In addition any mathematical number symbol written/typed around SCP-#### within thirty-two meter radius will cause a similar effect where the writer will forget a certain information that they knew except the information forgotten was random. The amnesia duration effect from SCP-#### seems to take effect even if the number was written is rational, irrational, transcendental, or imaginary.
All number that have been written/typed about or around SCP-#### will automatically appear on SCP-#### including the full name of the writer, the original information obtain from the writer itself, and the original number itself in mathematical symbol. SCP-#### is hypothesised to only write Arabic number only, although the effect can trigger with any universal mathematical symbol the writer assume as their number.
The paper is made of not made from a known usual paper material with a scent of chalk, while the ink used appears to be a blue marker similar to the one that a teacher might use on a whiteboard. This writing and paper by any mean cannot be removed by any means even if the person burn it, tear it away from SCP-####, scratch it, dip the paper in any water, or even replace the word since it will instantly appears again on a new paper.
Any attempt to inform the writer about their original information was whether indirectly or not will cause the informer to have one of his information spread to all the X nearest people around the informer where X is the rounded up remaining minutes of the writer amnesia period
Addendum: SCP-#### was discovered by Agent Percy at SunnySide Kindergarten Playtime specifically at class one-E inside toy box number three. Due to Agent Percy accidentally trigger SCP-#### when trying to make a phone call regarding the discovery, the current discovery date is unknown, but it is predicted to be the twenty seventh May, two thousand [EXPUNGED].
Testing Log: The following is a log of all tests performed upon SCP-####.
Subject: D-two seven one eight two
Number Typed: Four over seven
Result: Subject forget how to clean his teeth for the next thirty four minutes twenty eight seconds
Notes: It appears that SCP-#### do not round up the number typed.
Subject: D-one six one eight zero
Number Typed: zero
Result: Subject is neutralised by an unknown caused instantly, even with a high speed camera showing it died zero second upon finishing typing zero
Notes: I'm assuming that the subject is neutralised because zero is a neutral number? It's neither positive nor negative?
Subject: D-six nine three one
Number Typed: pi
Result: Subject forgot his escape plan in the next three hours eight minutes forty nine minutes.
Notes: Thank goodness we can see his escape attempt and prevent from it being happen.
Subject: D-two three one four zero
Number Typed: negative nine
Result: Subject have a more negative impact such as mental breakdown figuring out what his original information was and become more self harming to itself for the next forty nine hours
Notes: Subject forgot his mother's name, further test should not use big numbers to save up time. Her name was Cartman by the way.
Subject: D-eight six six zero
Number Typed: root two
Result: Subject becomes more irrational than before where subject forgot his childhood life in the next 1 hour twenty four minutes eighty five seconds
Notes: the eighty five seconds was rounded up to one minute and twenty five seconds but it is rounded up in our world numeric system not to SCP-####.
Subject: D-eight six six zero
Number Typed: square root of negative one
Result: Subject becomes unreal or nonexistent anymore for the next 1 hour
Notes: It said that the subject forget his crime, well not anymore.
Subject: D-eight six six zero
Number Typed: negative square root of negative one
Result: Subject becomes nonexistent for the next 1 hour before returning dead presumably due to his stress not knowing what his lost information was
Notes: Subject forget to bribe an unnamed guard, that son of a-.
Subject: D-two two four five
Number Typed: (euler constant)^(pi*square root of negative one)
Result:subject forgot how to use a gun for an hour and have a negative impact of depression and suicidal thoughts
Notes: SCP-#### apparently can calculate the number. Fascinating.
Subject: D-seven zero seven
Number Typed: six plus square root of six plus square root of negative six plus one over six
Result:subject forgot how his father birthdate like while thirty eight point seven hundred forty two percent of the body remained for eight hours thirty nine minutes ninety six second while the other sixty percent becomes nonexistent for six hour before returning
Notes: Good news is the percentage of the body can be explained by the number degree between the imaginary and real number. Bad news is I'm fucking traumatised by what I have to witness to the subject while I'm measuring him. Please assign me to another test.
Subject: D-five seven seven
Number Typed: a squared plus b squared is equal c squared
Result: nothing happened
Notes: SCP-#### is not wolfram Alpha, it is not a calculator either so do your research before testing! -O5.
Subject: D-five seven seven
Number Typed: zero to the zero
Result: subject mind is stuck in a loop and subject died of overthinking
Notes: SCP-#### is not wolfram Alpha, it is not a calculator either so do your research before testing! -O5.
Subject: D-nine nine eight
Number Typed: tangent (pi over two)
Result: subject mind is stuck in a paradox and terminated due to the paradox almost caused destruction during the test
Notes: I was not expecting that.
Subject: D-five four eight
Number Typed: one over zero
Result: test result undefined
Notes: What?

Number Typed:Draw a three by three magic square using one through nine
Result: fifteen hours subject forgetting how to spell
Notes: Is SCP-#### a math nerd or something?.
Subject: D-two five eight eight
Number Typed:Put random numbers
Result: Subject forgot how to talk in the next N hours based on the sequence subject wrote
Notes: What is the number N exactly? We are planning to use the same subject again. Bummer.
Subject: D-nine six five
Number Typed:Creates a semi magic square using one through nine
Result: Subject mind got frozen due the incompleteness of the square and then was removed from the test
Notes: Wait why are we doing this in the first place?
Subject: D-two six seven nine
Number Typed: Creates an eight by eight bimagic square using one through sixty four
Result: Subject forgot two separate things with different amnesia interval
Notes: When can we stoppppp?
Subject: D-three seven three two
Number Typed: Creates a pandiagonal four by four magic square
Result: Subject forgot how to breathe
Notes: Damnit
Subject: D-five four eight
Number Typed: Creates a three by three multiplicative magic square
Result: Subject forgot how to drink within the same magic constant hour period
Notes: You know what, we should be testing SCP-#### to a personnel or another SCP rather than this test subject.
Subject: D-five four eight
Number Typed: Creates a seven by seven additive-multiplicative magic square
Result: Similar to D-two six seven nine
Notes: Pattern noticed. Let's just stop here.
Subject: D-four seven four
Number Typed: Creates a twelve by twelve trimagic square
Result: Test Aborted
Notes: When I say stop, I mean it.
Notes: But for real we should try to use it to another SCP like SCP-thirty three with natural log of two or something. Approval pending.
