Answer: The correct answer is: " - 341 " .

____________

Explanation:

____________

-1 × 372 − -31 =

(-1 *372) −(-31) =

(-1*372) + 31 ; {since "subtracting a negative value" is the same value as "adding that value's positive value"} ;

= - 372 + 31

= - 341

____________

The answer is: " - 341 " .

____________

Note: Using the "Order of Operation rules":

PE MD AS ;

"Please Excuse My Dear Aunt Sally" ; → "mnemonic device" ;

In which "Parentheses" (if they occur) are considered first;

then: "Exponents" (if they occur):

then: "Multiplication and Division" (if any of these occur; from the left of the equation—and continuing to the right of the equation—in the order in which they occur; neither the multiplication nor the division take priority over each other);

then: "Addition and Subtraction: (if any of these occur; from the left of the equation—and continuing to the right of the equation—in the order in which they occur; neither the addition nor the subtraction take priority over each other).

____________

We are given the expression:

____________

→ " -1 × 372 − -31 " ;

____________

Note, there are no "parentheses" or "exponents";

There is "one" multiplication but no "division".

There is "no" addition; but there is "one" subtraction.

so, the multiplication comes first:

→ " -1 *372 = -372 ;

Now, let us continue with the "one" subtraction that remains:

" -372 − -31 " ;

→ {Note that "subtracting a negative value" is the same value as

"adding that value's positive value"} ;

So, " - 372 − -31 = -372 + 31 = - 341 . "

____________

The correct answer is: " - 341 " .

____________

Hope this helps!

Wishing you the best!

The answer is -403

The order of operations puts multiplication before subtraction. -1 x 372= -372, and -372-31= -403
