Answer 1

1 200 + 250 : 50 - 850 = 355

= 1 200 + 5 - 850 =

=1 205 - 850 =

= 355


95 - 450 : 90 x 2 = 85

= 95 - 5 x 2 =

= 95 - 10 =

= 85


8 x 15 - 640 : 20 + 12 =

= 120 - 32 + 12 =

= 88 + 12 =

=100


230 : 10 x 2 + 675 : 15 - 45 : 9 = 86

= 23 x 2 + 45 - 5 = 

= 46 + 45 - 5 = 

= 91 - 5 = 

= 86  


362 - 225 x 4 : 6 x 1 + 92 : 4 = 235 

= 362 - 900 : 6 + 23 =

= 362 - 150 + 23 =

= 212 + 23 =

= 235


700 : 100 x 36 - 23 x 21 : 7 - 170 = 13 

= 7 x 36 - 483 : 7  - 170 =

= 252 - 69 - 170 =

= 183 - 170 =

= 13
