Lawv yog cov commutative, associative, multiplicative tus kheej thiab distributive khoom . Kev sib txuas lus vaj tse : Thaum ob tus lej sib npaug ua ke, cov khoom lag luam yog tib yam tsis hais qhov kev txiav txim ntawm cov khoom sib npaug.
Ntawm no, yam khoom twg yog nws thaum koj muab los ntawm 1?
Tus kheej vaj tse ntawm kev sib npaug : Cov khoom ntawm 1 thiab tus lej twg yog tus lej ntawd.
Dab tsi yog 5 lub zog ntawm lej? Commutative Property , Associative Khoom , Distributive Property, Cov khoom ntiag tug ntawm Multiplication, Thiab Cov khoom ntiag tug ntawm Ntxiv.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog cov khoom ntawm kev sib npaug thiab kev faib?
Cov khoom no muaj xws li: lub commutative khoom ntawm multiplication, lub associative khoom ntawm multiplication, lub cov khoom ntiag tug of one (multiplying by one), the multiplication property of xoom, the faib khoom , faib los ntawm ib tug, faib los ntawm xoom, xoom raws li cov nyiaj faib, thiab faib tus lej tsis yog zero los ntawm
Plaub lub zog hauv lej yog dab tsi?
Paub cov khoom ntawm cov lej no yuav txhim kho koj txoj kev nkag siab thiab kev paub txog lej. Muaj plaub yam tseem ceeb ntawm tus lej: kev sib txuas lus , koom nrog , faib , thiab tus kheej . Koj yuav tsum paub txog txhua yam ntawm no.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Dab tsi yog cov txiaj ntsig ntawm kev rho tawm ntawm cov lej?
Properties of Integers Integer Property Addition Subtraction Commutative Property x + y = y + x x – y ≠ y – x Associative Property x + (y + z) = (x + y) + z (x – y) – z ≠ x – (y – z) Identity Property x + 0 = x = 0 + x – 0 = x ≠ 0 – x Kaw Property x + y ∈ Z x – y ∈ Z
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Rudolf Virchow thiab Robert Remak tau txais txiaj ntsig dab tsi rau kev txhim kho ntawm txoj kev xav ntawm tes?
Nws kuj tau txais nyob rau hauv thaum ntxov 1850s uas imbalances nyob rau hauv blastema ua rau cov kab mob. Virchow siv txoj kev xav tias txhua lub hlwb tshwm sim los ntawm cov hlwb uas twb muaj lawm los ua lub hauv paus rau cov kab mob cellular, lossis kev kawm txog kab mob ntawm cov cellular. Nws txoj haujlwm tau ua kom pom tseeb tias cov kab mob tshwm sim ntawm qib cellular
