How to write the four operations of 285 3000 380 36

First calculate the 3000-380 = 2620 in parentheses, then 285x2620 = 746700, and then 746700 36=, I hope it will help you.

<> count the inside of the brackets and then the outside of the brackets.

Four rules of transportation: first calculate multiplication and division and then add and subtract, calculate in order from left to right, and calculate the brackets first, 300-(76 40 3)=300-(

Hello, this question examines four operations, the one with parentheses is calculated first, and if it is multiplication and division in the parentheses, then it is calculated in order from left to right, so the calculation process is as follows:

Hope, thank you.

Summary. I wonder how 3000-1504 is calculated? How to list the equation.

Hello, the answer and process are as follows.

I know the answer, and you basically know it, but I don't know how to wait for him.

Good. I've been abusing the equation for a long time, and I haven't figured it out.

I write by hand. What do his two zeros look like.

Good. 10) Single digits.

I hope it will help you, if you don't know anything, you can consult the teacher Oh By the way, move Lao Min or move your little hand to give the teacher a thumbs up, thank you

So who is he looking for to borrow this?

Find the previous 0 to borrow.

Then 0 does not.

I borrowed from the previous 0, and this 0 didn't have it.

Then borrow from 3.

So 3 becomes 2

I hope it will help you, if you don't know anything, you can consult the teacher Oh By the way, move Lao Min or move your little hand to give the teacher a thumbs up, thank you

When x=o, the equation holds. When ≠ 0 is about 5, the equation does not hold.

No wonder there are operator notations in this question.

Original question (380+x) 25=(236+x) 17 Only a superior person can see it.

380+x）/25】×（25×17）=【236+x）/17】×（25×17）

380+x）×17=（236+x）

6460+17x=5900+25x

17x-25x=5900-6460

8x=-560

x=70 check.

Left side of equation = (380+70) 25

Equation right = (236+70) 17

So x=70 is the solution of the original equation.

Multiply and divide first, then add and subtract, 40 20 800 first
