Salut!

Calculeaza:

1)3×100:6-(200-20):9+45:5-5= 300:6=50

300:6-180:9+9-5= 30

==0

0

=

50-20+9-5=

30+9-5=

39-5=

34

2)700:(5×5×2×2)+700:5:5:2:2-700:100=

700:(10×10)+140:5:2:2-7=

700:100+28:2:2-7=

7+14:2-7=

7+7-7=

14-7=7

3)[22+3×3×3-4:4-50:(5+5)+7]:(8-8:8+9+34)=

[22+27-1-50:10+7]:(8-1+9+34)=

[49-1-5+7]:(7+9+34)=

[48-5+7]:(16+34)=

[43+7]:50=

50:50=1

4)2+5×7-3×10:10+1×6=

2+35-30:10+6=

37-3+6=

34+6=40

5)4+4+5×(6×6:6-6)+7-8:8×9=

4+4+5×(36:6-6)+7-1×9=

4+4+5×(6-6)+7-1×9=

4+4+5×0+7-1×9=

4+4+0+7-9=

8+7-9=

15-9=6

Afla nr necunoscut:

1)a+15821=34100

a=34100-15821

a=18278

2)b-538=1579

b=1579+538

b=2117

3)8051-c=999

c=8051-999

c=7052

4)a×5=725

a=725:5

a=145

5)a:7=68

a=68:7

a=9 rest 5

6)1052:a=2

a=1052:2
