Answer 1

Efectuam calculele si tinem cont de ordinea efectuarii acestora:

inmultire, impartire, adunare, scadere

a)

100-1758:2+ (15 031+ 35 999): 15 - 362-25=

100-879+51030:15-387=

-779+3402-387=2236

b)

[(11 352: 6 + 18): 10+ 19]:30=

[(1892+18):10+19]:30=

(1910:10+19):30=

(191+19):30=

210:30=7

c)

5 (25-7-3+24)-100-25-30=

5(15+24)-100-25-30=

195-100-25-30=

95-25-30=

70-30=40

d)

[5-25-(7-3+24)]-(100-25)-30=

(5-25-28)-75-30=

-48-75-30=

-123-30=-153
