1. First of all, two digits and two digits are multiplied. The number of the first digit plus the number of the second digit is written in front of the equal sign, for example, 13 × 15 =. First, write 18 under the equal sign as 100 digits and 10 digits, that is 180 digits, as the draft

Secondly, multiply the single digits of two two digit numbers to get the two digit numbers as tens and single digits, and add the numbers on the tens twice to get the correct answer, such as 15 × 13＝，5 × 3 for 15, 15 + 180 for 195

extended data:

the checking methods of multiplying two digits by two digits are as follows:

1. Use the commutation law of multiplication to calculate the exchange position of two multipliers again, such as 12 × 34 = 408, you can use the vertical to calculate 34 again × 12. See if the results are the same

2. Divide the calculated result by the multiplier, such as 12 × 34 = 408, use 408 ÷ 12 or 34, see if the result is equal to 34 or 12

5. 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!

How to write the vertical form of two digit multiplication in grade three × 31

18 × 31 = 558

useful, please adopt

7. The divisor is two digits
150 ÷ 75 = 2
first divided into 150 ÷ 75
found that 15 ÷ The quotient of 75 is definitely 0, and 0 is usually ignored here
then, look at the whole 150 ÷ 75, the quotient is found to be 2, which is written on the top of the quotient corresponding to 0
the result is 2
other algorithms are similar

8. How to write 99 / 11 for the vertical calculation of dividing two digits by two digits
turn left | turn right
99 ÷ 11 = 9
useful, please adopt.

9. For example, 32 times 12 means that the upper and lower numbers face each other. Multiply 2 of 12 with 2 and 3 respectively, and write them in the bottom. Then multiply 1 of 12 with 2 and 3 respectively, and add the proct. That is to say,
64
32

384
