Please give me 270 fractions of addition and subtraction

I would, I wouldn't play very simply, like one plus one equals two.

Hello: Stands for the score line.

If you want an answer, I can't help you, otherwise it will do you more harm than good.

I hope you understand and hope it helps.

You pick it first, I'll help you out.

Cramped, hehehaha, greetings, Wuhan.

Very good! You can ask questions and know the answers.

(Note: 3 2 read two-thirds).

5+6/1+11/6+6/513、x+3/1+4/1=6/114、x-（3/2+4/1）=12/1115、x+4/3-2/1=116、x
/3+4/8+4/1

7+(1+8 7) hands are sore. Hope.

I don't have the ability and energy to add and subtract so many fractions, but I can give you a few suggestions:

1. There are many workbooks on the market to train numeracy skills, if you want, you can buy a few to do.

2. If you are reluctant to spend money, you can come up with a few questions by yourself, and it is also a good exercise to solve the questions yourself.

In addition, I also want to tell you that the key to improving the level of computing requires more practice, but more importantly, be careful, and master some tricks, if you can do these, even if you do 100, even 50, 30, it is better than you do 300 dryly, after all, the problem is endless!

I hope you will improve your computing skills as soon as possible!
