Explicație pas cu pas:
a) 27,03–13,321–(17,481–14,19)=
27,03–13,321- 3,291=
13,709-3,291=
= 10,418
b) 18,37–10,15+1,763–(3,63-2,164)=
18,37–10,15+1,763–4,466=
8,22+1,763–4,466=
9,983-4,466
=5,517
c) (90,1–20,37)-[(13,721–5,991)–0,75]=
69,73–(7,73–0,75)=
69,73–6,98=
=62,75
d) (5,1–0,01)–[5,6–(0,999+0,001)–(7,8–5,23)]=
5,11–(5,6–1–2,57)=
5,11–(4,6–2,57)=
5,11–2,03
= 3,08
