Cov Multiplication Property of One (tseem hu ua Multiplicative Tus kheej ) hais tias: a⋅1=a Qhov no txhais tau hais tias txhua tus lej uas suav nrog 1 yuav nyob ntawm tus lej ntawd xwb. Kev sib ntau los ntawm 1 tsis hloov dab tsi.
Ib yam li ntawd, tib neeg nug, pes tsawg puas tuaj yeem yog tus kheej rau kev sib npaug?
Tus kheej Cov khoom ntawm Multiplication : Txhua tus naj npawb ib zaug yog tus lej qub. Zero yog cov tus kheej tus naj npawb ntxiv thiab ib qho yog tus tus kheej tus lej ntawm kev sib npaug.
Tsis tas li ntawd, qhov twg yog qhov sib npaug ntawm tus kheej 0 lossis 1? Hauv lwm lo lus, cov khoom ntawm txhua tus lej thiab xoom yog ib txwm xoom . Peb pom tias cov khoom ntawm txhua tus lej thiab xoom yog xoom . Multipplication Identity : Hauv lwm lo lus, cov khoom ntawm txhua tus lej thiab 1 yog tus lej nws tus kheej.
Yog li ntawd, dab tsi yog 3 yam khoom ntawm kev sib npaug?
Cov khoom ntawm multiplication yog faib, kev sib txuas lus , koom nrog , tshem tawm ib qho tseem ceeb thiab cov khoom nruab nrab.
Dab tsi yog tus kheej rau kev sib npaug ntawm tag nrho cov lej?
Tus kheej Khoom rau Multiplication : Cov Tus kheej Khoom rau Multiplication of Whole Numbers hais tias thaum tus nqi yog muab los ntawm ib qho khoom yog tus nqi ntawd; i.e., kev sib npaug los ntawm ib tug tsis hloov tus nqi ntawm ib tus lej . Ib tug hu ua multipplication tus kheej.
Pom zoo:
Qhov kev hloov pauv twg yog qhov sib npaug ntawm daim duab peb sab mus rau nws tus kheej?
Nqa lub equilateral daim duab peb sab mus rau nws tus kheej. Yog li, cov no yog cov kev xaiv teb cov lus teb kom raug: kev sib hloov ntawm 120 ° counterclockwise. tig 120 ° clockwise
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
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)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
