Calculeaza:

2+[4+(7×3×10-12:4)+100]=
[25:(3×3-4)+40]:15+3-5=
396:11-[750:25-144:(8×3:2)-18]=
[(59×76+78×69):2]-1933=
[1000-(43+43×9+78:3+199)]:5=

Answer 1

2+[4+(7x3x10-12:4)+100]=
 2+[4+(210-3 )+100]=
2+(4+207+100)=
2+ 311= 313

[25:(3x3-4)+40]:15+3-5=
[25:(9-4) +40]: 15+3-5=
(25:5+40):15+3-5=
 (5+40):15+3-5=
 45 : 15 +3-5=
    3 +3-5=
       6-5=1

396:11-[750:25-144:(8x3:2)-18]=
  36 -[30-144:(24:2)-18]=
   36-(30-144: 12-18]=
    36-(30-12-18)=
       36-(18-18)=
        36-0=36

[(59x76+78x69):2]-1933=
 [(4484+5382):2]-1933=
   (9866:2)-1933=
    4933-1933= 3000

[1000-(43+43x9+78:3+199)]:5=
 [1000-(43+387+26+199)]:5=
  (1000- 655):5=
     345:5=69

Answer 2

1)2+[4+(7x3x10-12:4)+100]=

2+(4+207+100)=2+311=313

2) [25:(3x3-4)+40]:15+3-5=

(25:5+40):15+3-5=

45:15+3-5=

3+3-5=1

3)396:11-[750:25-144(8x3:2)-18]=

396:11-(750:25-144:12-18)=

36-(30-12-18)=

36-0=36

4)[(59x76+78x69):2-1933=

(9866:2)-1933=

4933-1933=3000

5)[1000-(43+43x9+78:3+199)]:5=69
