C)-13+7-2-8+15-1
D)-2-4-1
E)(-8)+(-5)

​

Answer 1

Resposta:

A)

$- 8 + 6 - 1 = \\ \\ = - 2 - 1 \\ \\ = \boxed{ \LARGE \bf \green{ - 3}}$

B)

$( + 8) - ( + 5) = \\ \\ = + 8 - 5 \\ \\ = \boxed{\LARGE \bf \green{ + 3}}$

C)

$- 13 + 7 - 2 - 8 + 15 - 1 = \\ \\ = \pink{ - 13 + 7} \blue{- 2 - 8} \orange{ + 15 - 1} \\ \\ =(\pink{ - 6}\blue{-10})\orange{+ 14 }\\ \\ = - 16 + 14 \\ \\ = \boxed{ \LARGE \bf \green{- 2}}$

D)

$- 2 - 4 - 1 = \\ \\ = - 6 - 1 \\ \\ = \LARGE\boxed{ \bf \green{ - 7}}$

E)

$( + 8) + ( - 5) = \\ \\ = + 8 - 5 \\ \\ = \boxed{ \bf \LARGE \green{ + 3}}$
