Add the last digit (units digit) to twice the previous digit (tens digit). If this sum is divisible by 4, so is the original number.

Multiplying a number by 3 1/2 does not necessarily increase its value so the question is based on nonsense.

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.

The smallest 4 digit no is 1000. The smallest 2 digit no. is 10. Multiply these, you get 10,000. this is a 5 digit no. so the answer to your question is no. Multiplying one thousand by ten to get ten thousand is something you can do in your head in much less time than sending a question to wiki-answers. If you want to get better at math, start by always spending half a minute in thinking "is there an easy way to do this".

We call them by the number of their digits. Two-digit number, three-digit number and so on.

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.

product means multiplication. so a 2 digit number multiplied by a 4 digit number. 80 x 6250 = 500,000 80 can be your 2 digit number 6250 can be your 4 digit number

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.

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