How many ways can the number 10 be written as the sum of four odd digits?

In order to answer the question of how many ways you can write the number 10, as the sum of four odd digits. Let’s remember which numbers are called odd. Odd numbers are numbers that are not divisible by 2. Sum is a plus arithmetic. Therefore, the number 10 can be decomposed into the sum of four odd digits in this way: 3 + 1 + 5 + 1 = 10, 3 + 3 + 3 + 1 = 10, 7 + 1 + 1 + 1 = 10. So the number 10 can be decomposed into the sum of four odd digits in three ways. Answer: 3 + 1 + 5 + 1 = 10, 3 + 3 + 3 + 1 = 10, 7 + 1 + 1 + 1 = 10.
