What is 4O 7 first? 47 7 4 is what is counted first, and then what is counted

Count the single digit first, then ten, and if the single digit is not enough to subtract the ten, it is equal to 33

40-7, first count 40, 40 bits on the o, not enough for me to borrow one bit to become 10-7, equal to three. 4 borrows one bit and becomes three, and the answer is equal to 33

40 7 = 33 first calculate 0 is not enough to borrow 1 when 10, 10 7 = 3, four minus one equals three, 33 routine is a bit deep.

First calculate the single digit of 10 7 = 3 and borrow 1 from the ten digit, then 4 1 = 3, and the final number is 33.

Of course, it is 0 7 3, 4 1 3, and finally 33

First count borrowed 1. There are 3 left, and the last one is 33, have you learned?

40-7 is just 2 numbers. And calculate first and then count, isn't that 40-7 equal to 33?

The single digit "0" is preferred-"7", and the ten digits "4" are borrowed to you.

The result of subtraction is equal to 33

Count 40 7 first, and then do the math yourself.

40-7! Wouldn't such a simple question be?

The husband of the Kirin Ning generation.

It's too hard to ask. I don't know yet.

Hello! 40-7=33, the subtraction vertical operation is shown in the figure below.

Count the single digit first, then the ten. 47-4 should first calculate the number on the single digit and then calculate the ten-rent balance prudential position, because this is the characteristic of the decimal system, only from low to high, in order not to break the calculation order, will not make mistakes. The calculation method is to subtract the minus 4 by 7 on the 47 digits of the minus 4, and 7 minus 4 equals 3.

Then count the number in the tens place, and subtract the number in the tens with the 4 on the 47 bit. There is no number of numbers on the subtraction of dozens of digits, no need to subtract, or 4, the result of the single digit is, the ten digits are 4, and the combination is equivalent to first counting the single digits 7 + 7 = 14, 14 + 4 = 18, 18 + 40 first calculate the single digit 8 + 0 = 8, and then calculate the ten digits 1 + 4 = 5, ten digits + single digits = 50 + 8 = 58.

This public sale is the answer to the parentheses first.

When calculating the formula 3 9-(7-4), you need to calculate the operation in parentheses first, that is, 7-4=3, which should be calculated according to the principle of "multiplication and division first, then addition and subtraction".

Substituting 3 into the original formula gives the middle draft 3 9-3. Next, according to the principle of multiplication and division first, and then widening and subtraction, 3 9 is calculated first, that is, 27, and then 3 is subtracted, and the final result is 24.

Summary. Hello, first calculate 13-4=9, and then calculate 60+9 equals 69<><

73-4 Count first and then count nothing.

Hello, first calculate 13-4=9, and then calculate 60+9 equals 69<><

Dear, for the abdication subtraction, it should be counted like this<>

Dear, the above is the specific process and solution ideas, which step do you not understand, I can help you explain how to analyze?

Hello, there are seven tens and three ones in 73, which can be seen as seven bundles of small sticks and three single <>

Pro, if you want to laugh at the manuscript from seven tens, three and one to remove four, you have to open it first, a bundle of small sticks, and three together to touch Lingxiao is 13, first use 13 single roots minus 4 = 9 single roots, and then use six 10 and 9 together is 69 <>

Dear, I explain it like this, I believe you understand<>

How to calculate 32-5.

7-4 equals 3, and plus 7 is 3 plus 7 equals 10, so 7-4 plus plus 7 = 10.

Let me come to this question: the column formula of this question is 7+4+4=15, and the result is 15. Hope it helps.

Vertical calculations 14-7

Problem solving ideas: align the subtraction with the subtracted number, subtract the number from the corresponding counting unit respectively, if it is not enough to subtract, you need to borrow 1 from the high position, and calculate the result in turn, the subtraction is less than the subtracted number, and the final result of the two numbers will be converted and subtracted by adding a negative sign;

Problem solving: Step 1: 14-7=7 borrowing.

Step 2: 0-0=0

Step 3: The calculation result is 7

14-7

This can be used first.

Then use 10-3=7

Divide 7 into 3 and 4, first 14-4=10, then 10-3=7

Or divide 14 into 10 and 4, first 10-7=3, then 4+3=7

14-7, you can count 4-4 first, and then 10-3 equals 7.

In fact, the minus 7 is divided into 4 and 3, and West first subtracts the minus 4 from the 4 in the subtracted unit, and then subtracts the minus 3 with the remaining 10 of the minus 7

Count the single digit first, then the ten, and then the 7-4
