"Multiplying with 0 at the end of the multiplier" Multiplying two or three digits with one digit PPT courseware 3

Learn important and difficult points

Key points: Master the multiplication calculation method of multiplying one-digit numbers by three-digit numbers with zero at the end and be able to calculate accurately.

Difficulty: Understand the simple algorithm for multiplication of a one-digit number by a three-digit number with 0 at the end.

Multiplication 1 with 0 at the end of the multiplication

Oral arithmetic: 260×3

Divide 260 into 200 and 60, multiply each by 3, and finally add up the products. 200×3=600, 60×3=180, 600+180=780.

According to the vertical expression of the multiplication of three-digit numbers by one-digit numbers, align the one-digit number 3 with the "0" on the 260th digit. Multiply each three-digit number by 3.

Let the single digit 3 be aligned with the 6 before the 0 at the end of 260. Think of 260 as 26 tens, 26 tens times 3 places and 78 tens.

In conclusion

How to calculate the multiplication of a number with ; at the end: You can first use a single digit to multiply the number before 0 of another multiplier, and then look at how many 0s there are at the end of the multiplier. If there are several 0s, add a few at the end of the product. 0.
