Answer 1

Răspuns:

4. a) 325-186+243 = 139+243 = 382

106+782-858 = 888-858 = 30

30•8:6 = 240:6 = 40

45:5•30 = 9•30 = 270

b) 168+24•3 = 168+72 = 240

325-25:5 = 325-5 = 320

2•500-20•20 = 1000-400 = 600

500:2+68:4 = 250+17 = 267

c) (99+33)•3 = 132•3 = 396

(720-160):8 = 560:8 = 70

1000-(350-175) = 1000-175 = 825

900:(30•30) = 900:900 = 1

5. a) 34•2 = 68 (de pixuri)

34•6 = 204 (de creioane)

b) 84:(3+4) = 84:7 = 12 (buchete)

Prima problema se poate rezolva prin două moduri.

Sper că te-am ajutat! :)

Answer 2

4) a. 325-186+243=139+243=382

106+782-858=888-858=30

30*8/6 = 240/6=40

45/5*30 = 9*30=270

b. 168+24*3=168+72=240

325-25/5=325-5=320

2*500-20*20 = 1000-400=600

500/2+68/4=250+17=267

c. (99+33)*3=132*3=396

(720-160)/8=560/8=70

1000-(350-175)=1000-175=825

900/(30*30)=900/900=1

5) a. 34*2=68 - pixuri

34*6=204 - creioane

b. 84/(3+4)=84/7=12 - buchete
