9 + 9 = 18 + 18 = 36 + 36 = 72 + 72 = 144 + 144 what is the formula

9 + 9 = 18 + 18 = 36 + 36 = 72 + 72 = 144 + 144 what is the formula

I don't know where this formula comes from. I've seen similar ones. I'll introduce them to you as follows:
This may be to simplify the accounting algorithm. For the convenience of writing, many people omit one step and directly write the income or expenditure after the result of the previous step without another formula: that is, merging 1 + 1 = 2,2 + 2 = 4 into 1 + 1 = 2 + 2 = 4. Although it is unreasonable, it is more direct and clear. Some people should still use this accounting method
For example, the following accounts can be recorded as: 456-300 = 156 + 622 = 778 + 506 = 1284
Date income (expense)
8 456
9 -300
10 622
11 506
This notation does not conform to the law of mathematics and should be abolished!

How much is 40% of 500 bigger than 168

What is 40% of 500? 500 * 40% = 200
How much is 200 to 168? It's 200-168 = 32

According to 200-47 = 153153%, 3 = 51, 4 * 51 = 204, what is a comprehensive formula

The comprehensive formula should be:
（200-47）÷3×4=204

In a subtraction formula, the sum of the subtracted and the difference is 168, the subtraction is 3 / 4 of the difference, and the difference is?
Such as the title

Because the subtraction is 3 / 4 of the difference, the ratio of subtraction to difference is 3:4, 3 + 4 = 7
And because the subtracted = the subtracted + the difference
Each portion: 168 / (7 + 4) = 168 / 11
Poor: (168 / 11) * 4 = 672 / 11
