Question

1)Suprime los signos de agrupación.

A - 12+(45-(-16-18))-15
B -485-(162+(341-(-100+200)))
C -254+(-485-(-510+(-128-16)))
D -512+(-85-(-12+4-13))

2)Realiza las siguientes operaciones.

A (-25)+(30)+(-45)-(-18)
B (-25)(-4)(-3)
C -8(-12)(16)
D -45-64+78+36

Answer 1

A - 12+(45-(-16-18))-15
-12+(45-(-34))-15
-12+(45+34)-15
-12+(89)-15
-12+74
62-15= 52

B -485-(162+(341-(-100+200)))
-485-(162+(341-(100)))
-485-(162+(241))
-485-(162+241)
-485-(403)
-485-403
-888



C -254+(-485-(-510+(-128-16)))

-254+(-485-(-510+(-144)))
-254+(-485-(510-144))
-254+(-485-(-654))
-254+(485+654
-254+169
-85

D -512+(-85-(-12+4-13))
-512+(-85-(-21))
-512+(-85+21)
-512+(-64)
-512-64
-576



Operaciones:

A (-25)+(30)+(-45)-(-18)
(-25+30)+(-45+18)
25 -27
-2


B (-25)(-4)(-3)
-25*-4*-3
100*-3 => -300



C -8(-12)(16)
96*16=> 1536


D -45-64+78+36
(-45-64)+(78+36)
-109 + 114
