Clause. 3. Listen attentively in class and organize notes after class. I won't dwell on how important this is.

In order to improve the efficiency of class, you must carefully preview your homework before class. In class, don't copy your notes and miss the teacher's problem-solving ideas and summary, and the gains outweigh the losses. The notes are all sorted out and summarized after class.

432 54+17 54 Calculated by Li Ze's simple formula to eliminate the cover: take the disturbance.

8+17x54

8+(20-3)x54

Now we can extract the common factor 16 2 and get:

Now we can calculate the expression in parentheses and get:

So, the answer to the original question is:

Hello subject!

Let's take a look at the calculation like this, I think it's helpful, and I'm sorry to pass it. Thank you!

It can be expressed mathematically as: =(38-8)x26=30x26=780, I hope it can help you.

This is very good, the calculation of the union is very simple, since it is two 26, then you can 16 26-26 8, then equal to (16, minus 26) 8 is fine.

The simple operation method of 72x32+14x64 is: 72x32+14x2x32=32x(72+14x2)=32x(72+28)=32x100=3200
