Answer 1

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
