Question

(8-9)-(9+3)*5 5+(5+5+6)+9 (5/3-3) 2*3+(4*2)/2

Answer 1

Answer:

Step-by-step explanation:

Next time, please include the instructions.  I am assuming that the instructions state, "evaluate the following."

a) (8-9)-(9+3)*5  According to order of operations rules, we must do any work inside parentheses first, followed by any multiplication or division.  Here we calculate 8-9, obtaining -1, and 9+3, obtaining 12.  Then we have:

(-1) - (12)*5.  We must multiply here before subtracting:  -60 - 1 = -61.

b)  5+(5+5+6)+9    Do the addition inside parentheses first, obtaining:

5+(16)+9.  Now add up 5, 16 and 9:    30.

c) (5/3-3)    Do the division first, obtaining 5/3, and then subtract 3 (or, using the LCD, subtract 9/3):  5/3 - 9/3 = -4/3

d) 2*3+(4*2)/2  Do the multiplication first:  6 + (8)/2

Next, do the division:  6 + (4) = 10
