Ntawm no, nyob rau hauv cov kauj ruam hom, yog yuav ua li cas los daws qhov system nrog peb qhov sib npaug thiab peb qhov sib txawv:
- Xaiv ib qho ob khub ntawm qhov sib npaug ntawm qhov system.
- Tshem tawm qhov qub sib txawv los ntawm txhua tus khub siv txoj kev Ntxiv / rho tawm.
- daws cov txheej txheem ntawm ob qhov sib npaug tshiab siv txoj kev Ntxiv / rho tawm.
Kuj kom paub yog, koj yuav daws li cas rau ntau qhov sib txawv?
Txoj Kev 2 Kev daws qhov sib npaug sib npaug nrog tshem tawm
- Saib ntawm koj qhov sib npaug.
- Xaiv qhov sib txawv los tshem tawm.
- Ntxiv lossis rho tawm ob qhov sib npaug kom tshem tawm ib qho ntawm qhov sib txawv thiab daws qhov sib txawv.
- Txuas koj qhov kev daws teeb meem los daws qhov sib txawv ntawm qhov seem.
Tom qab ntawd, lo lus nug yog, koj yuav daws qhov system ntawm kev sib npaug li cas? Nov yog qhov nws mus:
- Kauj Ruam 1: Daws ib qho kev sib npaug rau ib qho ntawm qhov sib txawv. Cia peb daws thawj qhov sib npaug rau y:
- Kauj Ruam 2: Hloov qhov sib npaug mus rau lwm qhov sib npaug, thiab daws rau x.
- Kauj Ruam 3: Hloov x = 4 x = 4 x = 4 rau hauv ib qho ntawm qhov sib npaug qub, thiab daws rau y.
Kuj nug, 3 hom kev hloov pauv yog dab tsi?
Tej yam uas hloov pauv hauv kev sim hu ua sib txawv . A sib txawv yog ib yam dab tsi, zoo, los yog tej yam kev mob uas muaj nyob rau hauv txawv tus nqi los yog hom . Ib qho kev sim feem ntau muaj peb hom variables : ywj siab, nyob ruaj khov, thiab tswj tau.
Yuav ua li cas koj daws ib qho kev sib npaug ntawm ob qhov sib txawv?
Rau daws systems ntawm algebraic kev sib npaug muaj ob sib txawv , pib los ntawm tsiv lub sib txawv rau txawv sab ntawm lub kev sib npaug . Tom qab ntawd, faib ob sab ntawm lub kev sib npaug los ntawm ib qho ntawm cov sib txawv rau daws rau qhov ntawd sib txawv . Tom ntej no, coj tus lej ntawd thiab ntsaws rau hauv cov qauv rau daws rau lwm tus sib txawv.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Yuav ua li cas koj thiaj paub yog tias tus nqi sib npaug tsis muaj kev daws teeb meem?
Tus nqi tiag tiag ntawm tus lej yog nws qhov kev ncua deb ntawm xoom. Tus lej ntawd yuav yog qhov zoo, vim koj tsis tuaj yeem ua tsis zoo ob txhais taw deb ntawm ib yam dab tsi. Yog li txhua tus nqi sib npaug sib npaug sib npaug rau tus lej tsis zoo yog tsis muaj kev daws teeb meem, txawm tias tus lej ntawd yog dab tsi
Koj yuav txiav txim siab li cas yog tias qhov tsis sib xws tsis muaj kev daws teeb meem?
Cais tawm tus nqi tseeb ntawm sab laug ntawm qhov tsis sib xws. Yog tias tus lej ntawm sab nraud ntawm qhov tsis sib xws yog qhov tsis zoo, koj qhov kev sib npaug tsis muaj kev daws teeb meem lossis tag nrho cov lej tiag tiag li kev daws teeb meem. Siv cov cim ntawm txhua sab ntawm koj qhov tsis sib xws los txiav txim siab qhov twg ntawm cov xwm txheej no tuav
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Koj yuav daws qhov sib npaug li cas los ntawm kev cais qhov sib txawv?
Cov txheej txheem yooj yim los cais qhov sib txawv yog "ua ib yam dab tsi rau ob tog" ntawm qhov sib npaug, xws li ntxiv, rho tawm, sib npaug, lossis faib ob sab ntawm qhov sib npaug los ntawm tib tus lej. Los ntawm kev rov ua cov txheej txheem no, peb tuaj yeem tau txais qhov sib txawv ntawm ib sab ntawm qhov sib npaug
