Multiplication in general is important; not just 2-digit numbers.

The smallest four digit number is 1000. It is even so 1001 is the smallest four digit number that is odd.
The smallest four-digit number not using zero is 1000. In a four-digit number, the first digit cannot be zero, so the smallest possible value for the first digit is 1. The remaining three digits can be any number from 0-9, so the smallest possible four-digit number is 1000.

This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.

Well, honey, let me break it down for you. When you multiply a 4-digit number (ranging from 1000 to 9999) by a 1-digit number (ranging from 0 to 9), the result can be a 3-digit number (ranging from 0 to 8991). So no, the product of a 4-digit number and a 1-digit number is not always a 5-digit number. Math doesn't discriminate, darling.
Oh, dude, let me break it down for you. So, if you multiply a 4-digit number by a 2-digit number, the product can actually be either a 5-digit number or a 6-digit number, depending on the numbers you choose. It's like a surprise every time you hit that multiplication button! So, no, it's not always a 6-digit number, it's like a math lottery, man.

3 more than 5 is 8, so the tens digit is 8. The tens digit is,double the number of the ones digit, so divide 8 by 2 and you get 4. If you double 4 it is 8 so, the number is 84.
The four digit multiples of 1234 are:1234 (1234x1)2468 (1234x2)3702 (1234x3)4936 (1234x4)6170 (1234x5)7404 (1234x6)8638 (1234x7)9872 (1234x8)Multiplying 1234 by 9 give the 5 digit number 11106, so the largest 4 digit multiple of 1234 is 9872.
To find the number of 5-digit combinations from 1 to 20, we first calculate the total number of options for each digit position. Since the range is from 1 to 20, there are 20 options for the first digit, 20 options for the second digit, and so on. Therefore, the total number of 5-digit combinations is calculated by multiplying these options together: 20 x 20 x 20 x 20 x 20 = 3,200,000 combinations.

1We can not start a three digit number with 0, so 1 is the smallest digit.
