DOY CORONA A LA MEJOR RESPUESTA

Answer 1

(+30) - (-6) - (-18) + (+10) =

=36−(−18)+10

=54+10

=64

(+14) + (+6) - (+25) =

=20−25

=−5

(-15) - (-2) + (+8) + (+7) - (-20) =

=−13+8+7−(−20)

=−5+7−(−20)

=2−(−20)

=22

(-11) - (-5) - (-14) + (-3) =

=−6−(−14)−3

=8−3

=5

(-24) - (+16) + (-15) - (+9) + (-32) =

=−40−15−9−32

=−55−9−32

=−64−32

=−96

- (-250) + (-115) - (-89) =

=250−115−(−89)

=135−(−89)

=224

(-54) - (-19) + (-10) - (+26) + (+9) =

=−35−10−26+9

=−45−26+9

=−71+9

=−62

- (+16) + (-5) + (+13) - (+31) + (-121) =

=−21+13−31−121

=−8−31−121

=−39−121

=−160

(-25) + (-14) - (+20) - (-17) + (-65) - (+46) + (-19) =

=−39−20−(−17)−65−46−19

=−59−(−17)−65−46−19

=−42−65−46−19

=−107−46−19

=−153−19

=−172

- (-12 + 17 - 54 - 18 + 25 + 19 +26 - 11 - 33 - 20 + 115) =

=−(5−54−18+25+19+26−11−33−20+115)

=−(−49−18+25+19+26−11−33−20+115)

=−(−67+25+19+26−11−33−20+115)

=−(−42+19+26−11−33−20+115)

=−(−23+26−11−33−20+115)

=−(3−11−33−20+115)

=−(−8−33−20+115)

=−(−41−20+115)

=−(−61+115)

=−54
