What are the answers to the problems? And how do I show my work also?

Answer:
Answer to number one is 6. | 3 x 4 equals 12, and if you subtract 6 you're left with 6.
Answer to number two is 27. First I multiplied 6 and 4 together, I got 24, and then I added 3.
Answer to number three is 7. I added 4 and 2 together first, and got 6. And then I subtracted 6 from 13.
Answer to number four is -6. I first added 12 and 4 together and got 16, and then I subtracted that from 10, which gave me a negitive number.
Answer to number five is 36. I first multiplied 14 by 2, which gave me 28. And then I subtracted 28 from 64.
Answer to number six is 32. I first multiplied 12 and 2 together and then added 8.
Answer to number seven is 0. I first multiplied 4 and 6 together and got 24. And then I multiplied 2 and twelve together. 24 minus 24 equals 0.
Answer to number eight is 3. I subtracted 6 from 7 which gave me one, and then I added 2. (2 x 1 is two so you don't really need to show work for the multiplication on the right.)
Answer for number nine is 110. 5 x 2 is 10, so just add that to 100 and you have your answer.
Answer to number ten is 0. 10 + 15 = 25, and if you subtract 25 from 25 you get 0.
Answer to number eleven is 34. 24 divided by 4 is 6, so if you subtract 6 from 40 you get 34.
Answer to number twelve is 33. 6 x 5 equals 30, so add 3 to that and you have your answer.
Answer to number thirteen is 10. 5 x 4 equals 20, divide that by two and you have your answer.
Answer to number fourteen is 10. 10 divided by 6 is 2, and if you add 8 you have your answer.
Answer to number fifteen is 2. If you divide 16 by 2 you get 8. And then for the multiplication 3 x 2 is 6. So if you subtract 6 from 8 you get 2 which is your answer.
