Answer 1

a)824:8x5-150:3+97x7-408:8x6=41240−1503+(97)(7)−(4088)(6)=39737+(97)(7)−(4088)(6)=39737+679−(4088)(6)=40416−(4088)(6)=40416−24528=15888
b)89x8:4+295x8-950:5-48x7:2=7476+(295)(8)−9505−(48)(72)=7476+2360−9505−(48)(72)=9836−9505−(48)(72)=331−(48)(72)=331−3456=−3125
c)214+6x48-513:9-28x4+175:7:5=214+288−5139−(28)(4)+17575=502−5139−(28)(4)+17575=−4637−(28)(4)+17575=−4637−112+17575=−4749+17575=12826
d)1000-104x9+36x8+413:7x6-456:3=1000−936+(36)(8)+(4137)(6)−4563=64+(36)(8)+(4137)(6)−4563=64+288+(4137)(6)−4563=352+(4137)(6)−4563=352+24822−4563=25174−4563=20611
e)12000-36x25:3-651:7x9+736:4:8=12000−9108−(6517)(9)+73648=2892−(6517)(9)+73648=2892−58653+73648=−55761+73648=17887

Answer 2

a) 103 * 5 - 50 + 679 - 51 * 6= 515 - 50 + 679 - 306=838

b) 89 * 2 + 2360-190-336 : 2=178 + 2170 - 168=2180

c) 214 + 288 - 112 + 25 : 5=502 -112 +5=395

d)1000 - 936 + 288 + 59 * 6 - 152= 64 + 288 + 354 - 152=554

e)12000 - 900 : 3 - 93 * 9 + 184 : 8=12000 - 300 - 837 +23 = 11336
