To find how many three-digit numbers have a sum of 10, we can denote the digits as (a), (b), and (c), where (a) is the hundreds place, (b) is the tens place, and (c) is the units place. Since (a) must be between 1 and 9 (inclusive) and (b) and (c) can be between 0 and 9, we need to solve the equation (a + b + c = 10) with the constraints on (a). By systematically counting the valid combinations, we find there are 36 three-digit numbers where the sum of the digits equals 10.

How many numbers 10 through 93 have the sum of their digits equal to a perfect square?
To find how many numbers from 10 to 93 have the sum of their digits equal to a perfect square, we first identify the possible perfect squares within the range of digit sums. The digit sum of a two-digit number ranges from 1 (for 10) to 18 (for 93). The perfect squares in this range are 1, 4, 9, and 16. By calculating the digit sums for each number from 10 to 93, we can determine that the numbers with digit sums equal to these perfect squares are 10-19 (sum = 1, 4, 9), and some others up to 93, yielding a total of 38 numbers.

Find the sum of the smallest and biggest two-digit composite numbers?
The smallest two-digit composite number is 10, which is the product of 2 and 5. The largest two-digit composite number is 99, which is the product of 3 and 33. To find the sum of the smallest and largest two-digit composite numbers, we add 10 and 99, resulting in 109.

How many two-digit numbers have digits whose sum is a perfect square?
To find how many two-digit numbers have digits whose sum is a perfect square, we first note that the two-digit numbers range from 10 to 99. The possible sums of the digits (tens digit (a) and units digit (b)) can range from 1 (1+0) to 18 (9+9). The perfect squares within this range are 1, 4, 9, and 16. Analyzing each case, we find the valid combinations for each perfect square, leading to a total of 36 two-digit numbers whose digits sum to a perfect square.
How many 4 digit numbers have 6 as their second digit?
There are 9 digits that can be the first digit (1-9); for each of these there is 1 digit that can be the second digit (6); for each of these there are 10 digits that can be the third digit (0-9); for each of these there are 10 digits that can be the fourth digit (0-9). → number of numbers is 9 × 1 × 10 × 10 = 900 such numbers.
What are the 10 two digit prime numbers that are the sum of two prime numbers?
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
How many two digit numbers are there?
There are 90 two-digit numbers... starting with 10 and ending with 99.
