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:

Explicație pas cu pas:

25 x ( 160 - 15 ) - 8 + (24 + 1) = 25 x 145 - 8 + 25 = 3625 - 8 + 25 = 3642

120 / 6 - 180 / 9 + 9 - 2 = 20 - 20 + 9 - 2 = 7

16 / 8 x [30 + ( 8 / 2 - 1)] - 10 = 2 x (30 + 3) - 10 = 2 x 33 -10 = 66 - 10 = 56

9 + ( 9 - 9 ) + 220 - 0 = 9 + 0 + 220 - 0 = 229
