What is the calculation power of two digit by two digit

1. The multiplier is a two digit multiplication rule:

1. First, multiply the multiplicand by the number of the multiplier's bits, and the last bit of the multiplier is aligned with the number of the multiplier's bits

2. Multiply the multiplicand by the number on the ten digits of the multiplier, and the last digit of the multiplier is aligned with the ten digits of the multiplier

3. Then add up the two multiplied numbers.

(Note: in 1, we need to use the number in the multiplier bit to multiply the number in the multiplied bit. Then multiply the multiplier by the number on the tenth digit of the multiplicand. 2 li is the same)

wish you a happy life!

2.

The following two points should be paid attention to when calculating the multiplication of two digits by one digit in vertical column:

1. format requirements: in vertical column, the digits of two factors should be aligned. Generally, the two digits should be written on the top, and then the one digit should be written on the bottom for the two digit digit digit, It's right in front of that one.

3. Align the digit, pay attention to the digit alignment in the proct of ten hundreds, understand the calculation principle, master the algorithm, master the steps of division and the writing position of quotient

4. Priority attention is given to the number of positions, to be drawn up and understood by the number of attention at 10 per cent of the board, In control of the law, a written position of steps and steps of steps and positions of a written position in order to be held in order to be taken in the concept of law....

5. Hello, classmate, when you multiply two digits, you need to pay attention to that ten times one should fall on ten, and one times one should fall on one, so as not to add mistakes later.

6. The written algorithm of multiplying two digit numbers by two digit numbers
1. Multiply the first factor by one digit of the second factor, and the last digit of the number is aligned with one digit of the first factor,
2. Multiply the first factor by ten digits of the second factor, and the last digit of the number is aligned with ten digits of the first factor< Then add up the proct of the two times.

7. Multiplier is the multiplication rule of two digits:
1. First, multiply the multiplicand by the number of bits of the multiplier, and the last bit of the multiplier is aligned with the number of bits of the multiplier
2. Multiply the multiplicand by the number on the tenth digit of the multiplier, and the last digit of the multiplier is aligned with the tenth digit of the multiplier
3. Then add up the two multiplied numbers.
(Note: in 1, we need to multiply the number on the multiplier bit by the number on the multiplicand bit, and then multiply the number on the multiplicand bit by the number on the multiplicand bit by the number on the multiplicand bit by the number on the multiplicand bit by bit

8. The calculation method of multiplying two digits by two digits is as follows: first, multiply the number on the (th) bit of the second multiplier by the first multiplier, and the last bit of the number is aligned with the (th) bit; Then multiply the number of (10) bits of the second multiplier by the first multiplier, and the last bit of the number is aligned with (10); Then (add the proct of two times)

9. First, multiply each bit of one factor by another,
then multiply each bit of the other by ten bits of this factor,
finally, add the proct of the two times.
