Question

Calculeaza respectand ordinea efectuarii operatilor
a) 506+826:7-10×0=
b) 109×(5+936:6)-1007=
c) 27+100×[365-10×(30+30:6)]=

Answer 1

a) 506+826:7-10x0=624
826:7=118
10x0=0
506+118-0= 624
b)109x(5+936:6)-1007=16542
936:6=156
5+156=161
109x161-1007=
109x161=17549
17549-1007=16542
c)27+100x[365-10x(30+30:6)]=
30:6=5
30+5=35
27+100x(365-10x35)=
10x35=350
365-350=15
100x15=1500
27+1500=1527

Answer 2

a)faci intai impartire inmultirea si adunarea si ne da 624
b)facem intai paranteza apoi inultirea si scaderea si ne da 16543
c)facem intai paranteza rotunda su apoi paranteza patrata se transforma in paranteza rotunda pe care o rezolvi apoi imultirea si adunarea si ne da 39027
