first triple digit pentagonal pyramidal number is 126
126.
a single digit divisor is as single digit number ( 1 - 9) that can be evenly divided into a number. like the single digit numbers for 5670 is 1,2,3,5,6,7,9 . you know this cause all of though numbers can be divided evenly into 5670.. don't believe me ... ask your calculator? ps: i <3 jb
To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the hundredths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.

If you're in the UK, area code 020 is London. The '3' is the first digit of the local number, not the last digit of the area code.

A double digit number, triple digit number........
It is a number with two digits in it. So it goes into the "tens" place of the numbers. Basically any whole number from 10 to 99. See how any number between those numbers only has 2 numbers, or digits that make up the number? 9 would only be a single-digit number, and 100 would be a triple-digit number.
there are 999 - 100 + 1 = 900 positive triple digit positive integers, between 100 and 999.(e.g. there are 102 - 100 + 1 = 3 triple digit integers between 100 and 102,namely 100, 101 and 102.)multiply that by 2 to take in consideration of the negative integers,you have 1800 triple digit integers.
times equals sets of
30.The first digit can be one of three digits {3, 6, 9} corresponding to the last digit being {1, 2, 3}, and for each of those three digits, the middle digit can be one of ten digits {0 - 9}, making 3 x 10 = 30 such numbers.It is assumed that a 3 digit number is a number in the range 100-999, excluding numbers starting with a leading zero, eg 090 is not considered a 3 digit number (though it would be a valid 3-digit number for a combination lock with 3 digits).
Prime factor all three.Find LCM by factor rules.Double or triple until you get a 4 digit number.18=2x3x324=2x2x2x332=2x2x2x2x22x2x2x2x2x3x3=32x9=288288,576,864,1152
Divide the two-digit number by the one-digit number. If the remainder is zero then the 2-digit number is a multiple and if not, it is not.
No. When adding the smallest 2 digit number (= 10) to the smallest 2 digit number (again, 10) the result is a 2 digit number (10 + 10 = 20). When adding the largest 2 digit number (= 99) to the largest 2 digit number (again, 99) the result is a 3 digit number (99 + 99 = 198). As you can see, you'll either get a 2 or 3 digit number, but never a 4 digit number.
If your asking in a digit it's called a 4 digit number and it is the smallest 4 digit number
No.
