a) 824:8*5-150:3+97*7-408:8*6=

b) 89*8:4+295*8-950:5-48*7:2=

c) 214+6*48-513:9-28*4+175:7:5=

Answer 1

a) 824:8×5-150:3+97×7-408:8×6
=103×5-50+ 679-51×6
=515-50+679-306
= 465+679-306
= 1144-306
= 841

b)89×8:4+295×8-950:5-48×7:2
= 712:4+ 2360- 190- 336:2
= 178+2360-190-168
= 2538-190-168
= 2348-168
= 2180

c)214+6×48-513:9-28×4+175:7:5
=216+288- 57 - 112+ 25:5
=216+288-57-112+5
= 504-57-112+5
= 447-112+5
= 335+5
=340
