Well, isn't that a happy little math problem! Let's see, we can choose the odd numbers 1, 7, and 12 to make 20. Remember, there are many ways to approach a problem, so feel free to explore different combinations and see what works best for you. Just remember, there are no mistakes in math, just happy little accidents!

It is impossible to add eight odd numbers together to get an even sum like 20. The sum of any odd numbers is always odd if an odd count of them is used, and it becomes even only when an even count is used. Since eight is an even number, the sum of eight odd numbers would be even, but it will still exceed 20 since the smallest odd number is 1, and the sum of eight 1s is 8, which is less than 20. Thus, there are zero ways to add eight odd numbers to achieve a sum of 20.
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.

There are 20 odd numbers in 40.
There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.
There are 69 odd numbers between 20 and 158.
