Hauv ib ntxiv equation , addends yog cov zauv uas tau ntxiv ua ke los muab a sum . Hauv kev rho tawm kev sib npaug , lub subtrahend raug tshem tawm ntawm qhov minuend los muab qhov sib txawv. Nyob rau hauv ib tug multiplication kev sib npaug , yam tseem ceeb yog multiplied muab ib yam khoom.
Kuj nug, ua li cas koj sau ib qho kev sib npaug ntxiv?
Rau sau ib tug kom raug ntxiv equation , koj muaj ib lub cim sib npaug. Ib sab qhia koj tag nrho. Lwm sab qhia koj tias dab tsi ntxiv ua ke. Koj tuaj yeem muaj qhov sib txawv ntawm ob sab ntawm lub kev sib npaug.
Qhov thib ob, qhov teeb meem ntxiv hu ua dab tsi? Nws qhia koj ntxiv tus nqi ua ntej kos npe rau tus nqi tom qab kos npe. Ob qhov tseem ceeb hauv ib qho teeb meem ntxiv yog hu ua "ntxiv" thiab cov lus teb yog hu ua lub "sum." Koj tseem yuav pom ob qhov sib txawv layouts ntawm teeb meem ntxiv.
Tsuas yog li ntawd, Addition expression yog dab tsi?
Peb kawm tau li ntawd cov lus qhia ntxiv yog lej cov lus qhia uas muaj ntxiv tus neeg ua haujlwm. Kom yooj yim cov lus qhia ntxiv , peb muab cov ntsiab lus zoo li. Zoo li cov ntsiab lus yog cov uas qhia tib tsab ntawv los yog sib txawv nrog tib tus exponent.
Ib qho piv txwv ntawm ib kauj ruam sib npaug yog dab tsi?
Cov ntsiab lus ntawm yuav ua li cas los daws qhov sib ntxiv thiab rho tawm
| Hom kev sib npaug | Piv txwv | Thawj kauj ruam |
|---|---|---|
| Ntxiv equation | k + 22 = 29 k + 22 = 29 k + 22 = 29 | Tshem tawm 22 ntawm txhua sab. |
| Qhov sib npaug sib npaug | p − 18 = 3 p – 18 = 3 p – 18 = 3 | Ntxiv 18 rau txhua sab. |

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
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
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
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
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
