2 digit number
This is not true. Think about any 4 digit multiplied by 1. This remains a 4 digit. In the case of any 4 digit under 5000, multiplied by two would also be a 4 digit number
Since the greatest digit is 9 and the greatest 2-digit number is 99, the product of them is 891.
A double digit number, triple digit number........
32 is the smallest two-digit number that can be multiplied by itself to give a four-digit number. (32x32)=1024
Find a four digit number whose digits will be reversed when multiplied by nine?
That is correct. Considering the largest double digit whole number is 99. Unless of course, you mean adding the two digits of a double digit number alongside the two digits of another double digit number, then yes, you will have a 4 digit number. Depends how you interpret the question, and your creativity.
The negative three-digit number with the least value is -999.
There is no underlined digit. If there was it would be that digit multiplied by 10n-1 where n is the number of the digit as counted from the right hand end, starting at 1.
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.
Yes, unless the 3 digit number is negative, or a decimal.
32 (32 x 32 = 1024)
32 x 32 = 1024
I think you r cheating Mr.Cheater
add numbers below to each number at the top
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
