30+(26,2-1,6):1,23=
30+24,6:1,23=
30+20=50

(25,4-13,25):1,2+12,16=
12,15:1,2+12,16=
10125+12,16=22,285

(34,12+4,25):0,01-3837=
3837:0,01-3837=
3837-3837=0

b)

475,3+0,825:(0,03+0,3)=
475,3+0,825:0,33=

102+144,6:(28,9-14,44)=
102+144,6:14,46=
102+10=112

32,5:(42,6-39,35)+10,02=
32,5:3,25+10,02=
10+10,02=20,02

10:(12,4-12,3)-28,376=
10:0,1-28,376=
100-28,376=71,624

0,4•12,5+41=
5+41=46

d)

72,8:(2,9•1,3-2,17)-32,45=
72,8:(3,77-2,17)-32,45=
72,8:1,6-32,45=
