-

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

• parentheses, square brackets and braces.

The signs calculated in order are:

• multiplication/division, addition/subtraction.

The sign rules are

- ( - ) = +

+ ( + ) = +

- ( + ) = -

+ ( - ) = -

Resolution

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

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

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

$\large \sf = - 32 + 52 + 18$

$\large \sf = - 32 + 70$

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

So, the answer correct is 38
