The answer is -403

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

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

____________

Step-by-step 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 " .

____________

<u>Note</u>:  Using the "Order of Operation rules":

 PE MD AS ;

 "<u>P</u>lease <u>E</u>xcuse <u>M</u>y <u>D</u>ear <u>A</u>unt <u>S</u>ally" ; →  "mnemonic device" ;

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

              then:  "<u>E</u>xponents" (if they occur):

              then:  "<u>M</u>ultiplication and <u>D</u>ivision" (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:  "<u>A</u>ddition and <u>S</u>ubtraction: (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!

Pants are 25% if pants are $50 what is the new price
Contact [7]

Answer: $37.50

Step-by-step explanation: Assuming you mean 25% off and not 25% of the original price, first convert 25% to a decimal by dividing by 100. 25%/100=0.25. Multiply the price by 0.25. 50*0.25=12.5. Subtract the discount from the original price. 50-12.5=37.5.
