03456How to form a three digit multiplication multiplication formula for the maximum and minimum of

Analysis: If the three digits and hundreds cannot be 0, then there are 4 possibilities for the hundreds, and there are 4 numbers left, which can be made as tens, that is, there are 4 possibilities for the ten digits, and there are 3 numbers left, all of which can be for the single digits, that is, there are 3 possibilities for the single digits. The remaining two numbers are spelled into two digits, there are 2 possibilities, to sum up:

There are 3 kinds of possibilities for 4 * 4 * 3 * 2 = 96 to form a three-digit number, so that the first ten digits are zero, and there are 4 * 3 * 2 = 24 kinds. That is, the final answer is 4*4*3*2-4*3*2=72

The formula for the largest product is: 520x43 or 430x52.

520x43=22360

430x52=22360

This question examines the number of groups and multiplication calculations.

According to the meaning of multiplication and the nature of the multiplication equation, the larger the factor in the multiplication equation, the larger the product. The formula for the largest product is that the beginning of 5 forms a maximum three-digit number and the beginning of 4 forms a maximum two-digit number. Or 4 starts to form a maximum three-digit number, and 5 Kaiyou limbs form a maximum two-digit number, multiplied by it. So the formula with the largest product is 520x43=22360 or 430x52=22360.

Extended information: Maximum product: Use the largest number as the hundredth digit of a three-digit number, the second largest number as the tenth of a two-digit number, the third-largest number as the single digit of a two-digit number, the fourth-largest number as the tenth digit of a three-digit number, and the smallest number as the single digit of a three-digit number.

Minimum product: The smallest number other than 0 is used as the hundredth digit of a three-digit number, the second smallest number is used as the tenth of a two-digit number, the largest number in the remaining three numbers (including 0) is used as the unit of a three-digit number, the middle number is used as the unit digit of a two-digit number, and the smallest number is used as the tenth digit of a three-digit number.

Multiplication is a simple operation of addition, and division is a simple operation of subtraction. Subtraction and addition are inverses of each other, and division and multiplication are inverses of each other.

Several additions are added together, and the position of the addition can be arbitrarily exchanged; Or add a few additions and then add them to the other additions, and their sum does not change.

Use 02345 to form a multiplication formula for three-digit bending and selling rolls multiplied by two digits, and write the equation with the smallest remaining product: 345x20=6900.

The equation for multiplying three digits by two digits is the smallest: that is, the highest digit is the smallest, and the difference between the two digits is the largest. Matching.

Hope it helps!

There is a certain pattern to this kind of problem, but there is no guarantee that what you get is the correct result.

Upstairs, the minimum product is obviously wrong.

456 * 30 = 13680, this is the minimum product.

The largest equation is 630 54 = 3402o, and the smallest equation is 306 45 = 1377o!
