200-(13×2+26)+2-1=

Answer 1

9+117:9×12=9+13×12=9+156=165

{5×[9-(10-7)]+80}:10={5×[9-3]+80}:10=(5×6+80):10=(30+80):10=110:10=11

12×3:4+10-9=36:4+1=9+1=10

 (24+17)×(600-592)= 41×8=328

 200-(13×2+26)+2-1=  200-(26+26)+1=200-52+1=149

Answer 2

9 + 117 : 9 × 12 = 165
1) 117 : 9 = 13
2) 13 * 12 = 156
3) 156 + 9 = 165

{ 5 × [ 9 - ( 10 - 7 ) ] + 80 } : 10= 11, 5 
1) 10 - 7 = 3 
2) 9 - 3 = 6 
3) 5 * 6 = 35 
4) 35 + 80 = 115
5) 115 : 10 = 11, 5

12 × 3 : 4 + 10 - 9 = 10
1) 12 * 3 = 36
2) 36 : 4 = 9
3) 9 + 10 = 19 
4) 19 - 9 = 10

( 24 + 17 ) × ( 600 - 592 ) = 328
1) 24 + 17 = 41
2) 600 - 592 = 8
3) 41 * 8 = 328

200 - ( 13 × 2 + 26 ) + 2 - 1 =147
1) 13 * 2 = 26 
2) 26 + 26 = 52
3) 52 + 2 = 54
4) 54 - 1 = 53
5) 200 - 53 = 147
