The result correct of this expression is 38

-

In a numeric expression, we first resolve the numbers that are in symbol, such as:

  • parentheses, square brackets and braces.
<h3> </h3>

The signs calculated in order are:

  • multiplication/division, addition/subtraction.

\\

<h3>The sign rules are</h3>

- ( - ) = +

+ ( + ) = +

- ( + ) = -

+ ( - ) = -

\\

<h3>Resolution </h3>

\large \sf  =  - 32  -  ( - 52)  -  (15  -  33)

\large \sf   = - 32   + 52 -  (15  -  33)

\large \sf =   - 32   + 52 -  ( - 18)

\large \sf  =  - 32   + 52  + 18

\large \sf   = - 32   + 70

\pink{ \boxed{ \large \sf   = 38}}

So, the answer correct is <u>38</u>
