Explicación paso a paso:

1)5 + {(3 · 4) + [3 + (5 –2)]} =

5+(3)(4)+3+5−2

=5+12+3+5−2

=17+3+5−2

=17+3+3

=17+6

=23

2)[7 + (9 –4)] –12 =

7+9−4−12

=7+5−12

=12−12

=0

3)[(10 –3) –(4 + 1)] : 2 =

(10−3−(4+1))(2)

=(7−(4+1))(2)

=(7−5)(2)

=(2)(2)

=4

4)4 (2 +3) + {6 –[3 –(7 + 3)]} =

4(2+3)+6−(3−(7+3))

=(4)(5)+6−(3−(7+3))

=20+6−(3−(7+3))

=26−(3−(7+3))

=26−(3−10)

=26−(−7)

=33

5)70 –{21[18 + 25 –(50 -9)] : 7} =

70−21(18+25−(50−9))(7)

=70−21(43−(50−9))(7)

=70−21(43−41)(7)

=70−(21)(2)(7)

=70−(42)(7)

=70−294

=−224
