Rational number multiplication [- 10] * 3 * [- 1 / 2] * [- 5 and 1 / 3] * 4 / 5 [- 10] * 3 * [- 1 / 2] * [- 5 and 1 / 3] * 4 / 5 [- 17] * [- 2] * 34 * 0 * [125] 16 * [- 18] * 0.25 * [- 1] [- 4] * [+ 8.9] * [- 0.25] [- 2] - [+ 5 / 6] * [- 3 / 5] - 4-2 * 32 + [- 2 * 32] [7 / 6 + 5 / 4 + 3 / 18] * 36 [1 / 3 2 - [1 / 3-6 + 5 / 12] * 2.4] * 5

Rational number multiplication [- 10] * 3 * [- 1 / 2] * [- 5 and 1 / 3] * 4 / 5 [- 10] * 3 * [- 1 / 2] * [- 5 and 1 / 3] * 4 / 5 [- 17] * [- 2] * 34 * 0 * [125] 16 * [- 18] * 0.25 * [- 1] [- 4] * [+ 8.9] * [- 0.25] [- 2] - [+ 5 / 6] * [- 3 / 5] - 4-2 * 32 + [- 2 * 32] [7 / 6 + 5 / 4 + 3 / 18] * 36 [1 / 3 2 - [1 / 3-6 + 5 / 12] * 2.4] * 5

Question 1: original formula = - 1000 times negative half times negative 16 / 3 times 4 / 5 = negative 6400
Question 2: 0 (there is one in the middle multiplied by 0, so you don't need a process to get zero directly)
Question 3: the original formula = 16 times 0.25 times - 18 times - 1 = 72
Question 4: original = - 2 plus (negative half) - 4-64-64 = - 133.5
Question 5: original formula = 7 / 9 times 36 minus 5 / 6 times 36 plus 3 / 4 times 36 minus 7 / 18 times 36 = 28-30 + 27-14 = 11
Question 6: original formula = [5 / 3 - (7 / 12) multiplied by 2.4] multiplied by 5 = (5 / 3-7 / 5) multiplied by 5 = (respectively multiplied by) 25 / 3-7 = 4 / 3
I've tried my best to put all the processes and ideas in it, but I have a little habit of answering math problems. I may make some small mistakes, only limited to the results. I won't tell you if I add them or not. I'm random. If you want to study hard, you can do it again. If you don't want to study hard, you can't be all right, That's enough for me. But I didn't say there must be a mistake. It's random. Bear boy, I suggest you do it by yourself, otherwise it's meaningless for me to do it. It's no nonsense. I don't want to ask for wealth
