Question

Calculeaza respectand ordinea efectuarii operatiilor:

25x(160-3x5)-8+(24+6:6);

12x10:6-(200-20):9+36:4-2;

4x4:8x[30+(64:8:2-1)]-10;

9+(9x9:9-9)+220-20x0;

Answer 1

Răspuns:

1. 25x(160-3x5)-8+(24+6:6)=25x(160-15)-8+(24+1)=25x145-8+25=3625-8+25=3642

2. 12x10:6-(200-20)9+36:4-2=120:6-180:9+9-2=20-20+9-2=7

3.

4x4:8x[30+(64:8:2-1)]-10=16:8x(30+3)-10=2x33-10=66-10=56

4.

9+(9x9:9-9)+220-20x0=9+0+220=229
