Answer:
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
