	Saothar suntasach (1557) The Whetstone of Witte ;

Ba dhochtúir agus matamaiticeoir Angla-Breatnach é Robert Recorde (c. 1512 – 1558). Cheap sé an tsín chothroime (=) agus chuir sé an comhartha suimithe (+) a bhí ann roimhe seo isteach do chainteoirí Béarla sa bhliain 1557.

Beathaisnéis cuir in eagar

Rugadh Robert Recorde timpeall na bliana 1512, agus ba é an dara mac agus an ceann deireanach é ag Thomas agus Rose Recorde ^[1] as Dinbych-y-pysgod, Sir Benfro, sa Bhreatain Bheag .

Chuaigh Recorde isteach in Ollscoil Oxford thart ar 1525, agus toghadh é ina Chomhalta de Choláiste na Marbh Uile (Laidin: Collegium Omnium Animarum Fidelium Defunctorum de Oxonia) ansin é sa bhliain 1531 . Tar éis dó an leigheas a ghlacadh mar ghairm, chuaigh sé go dtí Ollscoil Cambridge chun an chéim MD a dhéanamh i 1545. D’fhill sé ina dhiaidh sin ar Oxford, áit ar mhúin sé an mhatamaitic go poiblí, mar a bhí déanta aige sula ndeachaigh sé go Cambridge. Cheap sé an an tsín chothroime. Dealraíonn sé go ndeachaigh sé go Londain ina dhiaidh sin, agus gur ghníomhaigh sé mar dhochtúir don Rí Éadbhard VI agus don Bhanríon Muire, dá bhfuil cuid dá leabhair tiomnaithe dóibh. Bhí sé ina Ard-reachtaire Mionta agus Airgead in Éirinn.^[2] Tar éis do namhaid polaitíochta é a agairt mar gheall ar chlúmhilleadh, gabhadh é mar gheall ar fhiacha agus fuair sé bás i bPríosún Binse an Rí, Southwark, faoi lár mhí an Mheithimh 1558 .

An chéad chothromóid aitheanta, comhionann le 14x + 15 = 71 sa nodaireacht nua-aimseartha, ó The Whetstone of Witte . (Is é an réiteach na x = 4)

An tsín chothroime a thug Recorde isteach san 'The Whetstone of Witte', "to avoid tedious repetition"..

D’fhoilsigh Recorde roinnt saothar ar ábhair matamaitice agus leighis, go príomha i bhfoirm idirphlé idir máistir agus scoláire, mar a leanas:

The Grounde of Artes, a theagascann Worke and Practise, na hUimhríochta, i slánuimhreacha agus i gcodáin (1543), an chéad leabhar Béarla ar ailgéabar .
The Pathway to Knowledge, ina bhfuil na Chéad Phrionsabail Céimseata ... bac le húsáid Instrumentes Geometricall agus Réalteolaíocht, agus freisin le haghaidh Projection Plattes (Londain, 1551)
Caisleán an Eolais, ina bhfuil Míniú na Sféar araon Celestiall agus Ábhartha, etc. (Londain, 1556) Leabhar a mhíníonn an réalteolaíocht Ptolemaic agus é ag tagairt do shamhail heliocentric Copernican agus é á rith.
The Whetstone of Witte, atá mar an dara cuid de Arithmeteke: ina bhfuil eastóscadh fréamhacha; an cleachtas cossike, le riail na cothromóide; agus saothair Surde Nombers (Londain, 1557). Ba é seo an leabhar inar tugadh an comhartha comhionann isteach in eagrán clóite.^[3] Le foilsiú an leabhair seo tugtar creidiúint do Recorde as an ailgéabar a thabhairt isteach in Oileán na Breataine le nodaireacht chórasach.^[4]^[5]
Saothar leighis, The Urinal of Physick (1548), a athchló go minic.^[6]

Scríobhadh an chuid is mó de na saothair sin i bhfoirm caiticeasma.^[3] Tá roinnt leabhar a bhfuil a n-údar anaithnid curtha i leith dó: Cosmographiae isagoge, De Arte faciendi Horologium agus De Usu Globorum et de Statu temporum.^[7]
