Answer 1

Answer:

Step-by-step explanation:

(-437-1+8) +(234-(-10) -(15+(-17)) b) 509-(-19) +(-19)+20+(-20)

Answer 2

The given question is that we have to evaluate the above expression.

The given expression is 509-(-19)+(-19)+20+(-20)

The next step to the given question is

$509 - ( - 19) + ( - 19) + 20 + ( - 20)$

$( - ) \times ( - )$=+

we change into positive so the exact and expanded form of the equation is

$509 + 19 - 19 + 20 - 20$

The like terms with different signature will get cancelled.

$509 + (19 - 19) + (20 - 20)$

$509 + (0) + (0) \\ 509$

The final answer to the given question is 509.

Hence, therefore the answer to the given evaluation is

$509 - ( - 19) - 19 + 20 - 20 = 509$
