Rau ua algebra , ib txwm daws teeb meem siv qhov kev txiav txim ntawm kev ua haujlwm, uas yog kab lus, exponents, multiplication, division, ntxiv, thiab rho tawm. Piv txwv li, koj yuav daws txhua yam nyob rau hauv kab lus ua ntej, ces daws cov exponents, ces ua txhua qhov sib npaug, thiab lwm yam.
Kuj paub, dab tsi yog cov cai ntawm algebra?
Cov Basic Cov cai ntawm Algebra yog cov kev cai sib koom, kev sib txuas lus thiab kev faib tawm. Lawv pab piav qhia txog kev sib raug zoo ntawm tus lej ua haujlwm thiab qiv rau kev ua kom yooj yim sib npaug lossis daws lawv. Qhov kev npaj ntawm addends tsis cuam tshuam rau tus lej. Kev npaj ntawm yam tsis cuam tshuam rau cov khoom.
Ib sab saum toj no, ua li cas koj hla pre algebra? Tsom ntsoov rau kev kawm cov hauv paus ntsiab lus zoo, thiab koj yuav muaj peev xwm dhau qhov nyuaj pre-algebra chav kawm tau yooj yim.
- Pre-algebra Terminology. Kev nco cov ntsiab lus yuav tsis zoo li kev lom zem, tab sis pre-algebra yog tsim los ntawm cov ntsiab lus yooj yim.
- Nkag siab qhov sib npaug.
- Taug qab koj txoj haujlwm.
- Tau txais kev pab.
Ib yam li ntawd, tib neeg nug, koj siv algebra rau dab tsi?
Qee cov tub ntxhais kawm xav li ntawd algebra zoo li kawm lwm yam lus. Qhov no muaj tseeb rau me me, algebra yog ib hom lus yooj yim siv los daws cov teeb meem uas daws tsis tau los ntawm tus lej ib leeg. Nws tsim cov xwm txheej tiag tiag los ntawm kev siv cov cim, xws li cov tsiaj ntawv x, y, thiab z los sawv cev rau cov lej.
Cov qauv rau algebra yog dab tsi?
Algebra Formulas
- (a + b) 2 = a 2 + b 2 + 2 ab.
- (a - ib) 2 = a 2 + b 2 - 2 ib.
- a 2 -b 2 = (a − b) (a + b)
- (x + a) (x + b) = x 2 + (a + b) x + ab.
- (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2bc + 2ca.
- (a + (−b) + (−c)) 2 = a 2 + (-b) 2 + (-c) 2 2a (−b) + 2 (−b) (−c) + 2a (−c) (a – b – c) 2 = a 2 + b 2 + c 2 - 2ab + 2bc − 2ca.
