Question

Calcule o valor das expressões

40-[5.5+(2.2.2-7)]


50-{15+[4.4:(10-2)+5x2]}

15+(-4).(+3-10=

5.5+raíz de9 -[(+20):(-4)+3]

Answer 1

40-[5.5+(2.2.2-7)]
40-[5.5+(8-7)]
40-[5.5+1]
40-[26]
14

50-{15+[4.4:(10-2)+5x2]}
50-{15+[4.4:8+5x2]}
50-{15+[16:8+10]}
50-{15+12}
50-27
23

15+(-4).(+3-10)=
15+(-4).(-7)
15+28
43

5.5+raíz de9 -[(+20):(-4)+3]
5.5+raíz de9 -[-5+3]
5.5+raíz de9 -[-2]
5.5+raíz de9 +2
25+3+2
30

Answer 2

= 40 - [5.5 + (2.2.2 - 7)]
= 40 - [25 + (8 - 7)]
= 40 - [25 + 1]
= 40 - 26
= 14

******************

= 50 - {15+[4.4:(10-2)+5x2]}
= 50 - {15 +[16: 8 + 10]}
= 50 - {15 +[ 2 + 10]}
= 50 - {15 + 12} 
= 50 - 27
= 23

******************

= 15+(-4).(+3 - 10) =
= 15 - 4. (- 7)
= 15 + 28
= 43

***************************

= 5.5+raíz de9 -[(+20):(-4)+3]

= 25 + √9 - [ - 5 + 3]

= 25 + 3 - [ - 2]

= 28 + 2

= 30
