To solve this question, first you do 3 multiplied by 3=9. Then 9-3=6. After, multiply 6 by 2=12. Next, 12 multiplied by 10=120. Finally, it's 120 divided by 5!, and to do that you have to use the factorial (!). That's 5 multiplied by all the numbers below it, which is 120. So it's 120 divided by 120=1, and so that's the answer.
