  1. Kauj ruam 1: cais cov tus nqi kiag kev qhia.
  2. Kauj ruam 2: Teem kom muaj nuj nqis hauv lub tus nqi kiag notation sib npaug rau + thiab - qhov ntau ntawm lwm sab ntawm lub kev sib npaug .
  3. Kauj Ruam 3: daws rau qhov tsis paub hauv ob qho tib si kev sib npaug .
  4. Kauj Ruam 4: Tshawb xyuas koj cov lus teb analytically lossis graphically.

Ntawm no, koj yuav ua li cas daws cov nqi sib npaug thiab qhov tsis sib xws?

Koj pib los ntawm kev ua nws ua ob qho sib cais kev sib npaug thiab tom qab ntawd daws lawv cais. Ib tus nqi sib npaug tsis muaj kev daws teeb meem yog tias cov tus nqi kiag kev qhia sib npaug ntawm tus lej tsis zoo txij li ib tus nqi kiag yeej tsis tuaj yeem ua tsis zoo. Koj tuaj yeem sau ib qho tus nqi tsis sib xws raws li kev sib xyaw kev tsis sib xws.

Tsis tas li ntawd, tus nqi tiag tiag rau 4 yog dab tsi? Tus nqi kiag piav qhia qhov kev ncua deb ntawm tus lej ntawm tus lej kab ntawm 0 yam tsis xav txog qhov kev taw qhia ntawm xoom tus lej dag. Cov tus nqi kiag ntawm tus lej yeej tsis muaj qhov tsis zoo. Cov tus nqi kiag 5 yog 5.

Yog li ntawd, dab tsi yog cov cai rau tus nqi tiag?

Thaum peb muab lub tus nqi kiag ntawm tus lej, peb ib txwm xaus nrog tus lej zoo (lossis xoom). Txawm hais tias qhov kev tawm tswv yim yog qhov zoo lossis tsis zoo (lossis xoom), cov zis yog ib txwm zoo (lossis xoom). Piv txwv li, | 3 | = 3, thiab | –3 | = 3 too.

Tus nqi ntawm 3 yog dab tsi?

Piv txwv li, lub tus nqi kiag li ntawm 3 yog 3 , thiab cov tus nqi kiag ntawm - 3 kuj yog 3 . Cov tus nqi kiag ntawm tus lej yuav xav tias nws nyob deb ntawm xoom.
