{[3 + 2 - (9 - 7) + (3 + 4)]

7

youd do 9-7= 2

3+4= 7

3+2-2+7 is your equation now and you can do this left to right like normal

5-2+7

3+7

10

Step-by-step explanation:

The order of operations is applicable in a multip-operations equation. This theorem states the order in which one must do operations in order to get a valid result. Remember the order of operations states;

1) Parenthesis

2) Exponents

3) Multiplication or Division

4) Addition or Subtraction

Solve this equation, keeping the order of operations in mind;

{ [ 3 + 2 - ( 9 - 7 ) + ( 3 + 4 ) ] }

{ [ 3 + 2 - ( 2 ) + ( 7 ) ] }

{ [ 3 + 2 - 2 + 7 ] }

{ [ 5 - 2 + 7 ] }

{ [ 3 + 7 ] }

{ [ 10 ] }

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
