Answer 2
If you half it and you get a multiple of 3, then what you are saying is it is a multiple of 6 (2 x 3 = 6).
So you want a 4 digit number, a number between 1000 and 9999, which is a multiple of 6.
The lowest is 1002 (= 6 x 167), followed by 1008, 1014, 1020 ... etc. up to 9996 (= 6 x 1666).
So, there are a total of 1500 such numbers.

Why does a 4 digit number take away another 4 digit number equal a multiple of 9?
It doesn't always. It's true only if the 4-digit numbers are mirror images of each other.
Why do not all multiples of four end in four?
Quite simply, there is no rule that states that all multiples of a one-digit number have to end with that same digit, and no reason why it should be so. In the case of 2, and simply because 10 is a multiple of 2, the last digit (of a multiple of 2) is also a multiple of 2 - but it doesn't even have to be 2; it can be 0, 2, 4, 6, 8. Similar with 5, since 10 is also a multiple of 5. In the case of 4, since 100 is a multiple of 4, the last two digits of any multiple of 4 are a multiple of 4. For instance, take the number 4524 - since the last two digits (24) are a multiple of 4, the whole number is. Suggestion: Take some multiples of 4 (or of some other number), and try to look for patterns. Note that for some numbers, the patterns are so complicated, that it's easier to figure out whether a number is a multiple of another by actually doing the division.
What is the predecessor of smallest 6 digit even number?
Take the smallest 6-digit even number, then subtract one from it.
What is a multiple of 9 a 3 digit number below 200 the product of its digits is sixteen?
Impossible. With all multiples of nine the product of its digits is 9. Take, for exampe, 117 or 153.
What does it mean to round a number to the nearest thousand?
When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the hundreds place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.
Why do you always get a multiple of 9 when you take a smaller 4 digit number from a larger 4 digit number?
The question asserts something that is not true. For example, 2000 - 1000 = 1000. 1000 is not a multiple of 9.
Why does a 4 digit number take away another 4 digit number equal a multiple of 9?
It doesn't always. It's true only if the 4-digit numbers are mirror images of each other.
Why cant a number that ends on 3 be a multiple of 4?
Any multiple of four must be even; any number ending in three is odd. Look at the multiples of four from 1 to 9. They are in the order : 4,8,12,16,20,24,28,32,36. Now, any number when multiplied by 4, will have the one's digit as the one's digit of the above multiples In the above multiples, no multiple has 3 as the one's digit, i.e., no multiple ends in three. Take an example. 15x4 will have 0 in the one's digit because 5x4 = 20 and has 0 in the one's place.

The rule of the multiple of 7?
If you take the units digit and double it then subtract it from the rest of the number then the difference is divisible by seven. You may have to do it several times. 574 57-8=49 So it is a multiple of 7.
What is the predecessor of smallest 6 digit even number?
Take the smallest 6-digit even number, then subtract one from it.
What is the divisibility rule for 4 7 8?
4- last two digits are a multiple of 4 7-take the last digit and subtract it from the rest of the number and if multiple of 7 (including 0) 8- last three digits are multiple of 8
What is the divisibility rule for 91?
The number must meet two criteria:Take the original number excluding its last digit and subtract two times the last digit from it. The result must be divisible by 7.Take the original number excluding its last digit and subtract nine times the last digit from it. The result must be divisible by 13.In both cases, you can repeat the "truncate-and-subtract multiple" stage several times, if required.

Find a prime number that if multiplied would generate a 400 digit number?
The answer is vague but correct . Take any prime number and any other number whose combined digit length is 401 and their product will generate a 400 or a 401 digit number.
What 9 digit number is divisible by 9 and if you take off the 9th digit the number is divisible by 8?
