Answer 1

Răspuns:

a=1+2x{3+4x[5+6x(7+8x9)-333]-444}-222

a=1+2x{3+4x[5+6x(7+72)-333]-444}-222

a=1+2x[3+4x(5+6x79-333)-444]-222

a=1+2x[3+4x(5+474-333)-444]-222

a=1+2x[3+4x(479-333)-444]-222

a=1+2x(3+4x146-444)-222

a=1+2x(3+584-444)-222

a=1+2x(587-444)-222

a=1+2x143-222

a=1+286-222

a=287-222

a=65

b=2360:472+7885:[24+(13+43x34):(8901:43-13x14)]

b=5+7885:[24+(13+1462):(207-182)]

b=5+7885:(24+1475:25)

b=5+7885:(24+59)

b=5+7885:83

b=5+95

b=100

c=[4000-38x(1+2x3+4x5+6x7)]:2-36x19

c=[4000-38x(1+6+20+42)]:2-684

c=(4000-38x69):2-684

c=(4000-2622):2-684

c=1378:2-684

c=689-684

c=5

n=(2a-b):c+c

n=(2x65-100):5+5

n=(130-100):5+5

n=30:5+5

n=6+5

n=11
