Question

Calcule o valor das seguintes expressões numéricas
A) 50-{15+[16:(10-2)+5.2]}

B)  70-[5(4:4)+9]

C) 25+{27:9+[9.5-3(8-5)]}

Answer 1

A)
50-{15+[16:(10-2)+5.2]}
50-{15+[16:8+5.2]}
50-{15+[2+10]}
50-{15+12}
50-27=23


B)  70-[5(4:4)+9]
70-[5.1+9]
70-14=56

C) 25+{27:9+[9.5-3(8-5)]}
25+{27:9+[9.5-3.3]}
25+{27:9+[45-9]}
25+{27:9+36}
25+{3+36}
25+39=64
