cuanto dan es urgentisimo

Answer 1

1.10−(8+4)

=10−12

=−2

2.

6−(3−12)

=6−(−9)

=15

3.5+7−(2−8)

=12−(2−8)

=12−(−6)

=18

4.18+3−5+2−8

=18+−2+2−8

=18+0−8

=18+−8

=10

5.15−(8−2−6+1)

=15−(6−6+1)

=15−(0+1)

=15−1

=14

6.=2+2−(10−5−3+1)

=4−(10−5−3+1)

=4−(5−3+1)

=4−(2+1)

=4−3

=1

7.=−2−(−2−7)

=−2−(−9)

=7

8.=−9+−2−3

=−9+−5

=−14

9.=12−(−5−14)

=12−(−19)

=31

10.=8−(6+5−9−(16−8−11))

=8−(6+−4−(16−8−11))

=8−(2−(16−8−11))

=8−(2−(8−11))

=8−(2−(−3))

=8−5

=3
