Answer 1

6 800 - 1 648 : 8 + 78*4 = 6 906
1) 1 648 : 8 = 206
2) 78*4 = 312
3) 6 800 - 206 + 312 = 6 906

31 100 - (4 180*3 + 236*8) = 16 672
1) 4 180*3 = 12 540
2) 236*8 = 1 888
3) 12 540 + 1 888 = 14 428
4) 31 100 - 14 428 = 16 672

(2 600 - 2 320) : 4 + 140*3 = 490
1) 2 600 - 2 320 = 280
2) 280:4 = 70
3) 140*3 = 420
4) 70 + 420 = 490

5 110*6 - 99 : 33 = 30 657
1) 5 110*6 = 30 660
2) 99 : 33 = 3
3) 30 660 - 3 = 30 657

8 130*5 + 72 : 24 = 40 653
1) 8 130*5 = 40 650
2) 72 : 24 = 3
3) 40 650 + 3 = 40 653

7 150*6 - 70 : 14 = 42 895
1) 7 150*6 = 42 900
2) 70 : 14 = 5
3) 42 900 - 5 = 42 895
