What is the sum of even numbers that are greater than 10 but less than 20?
The even numbers greater than 10 but less than 20 are 12, 14, 16, and 18. To find the sum, we add these numbers: 12 + 14 + 16 + 18 = 60. Therefore, the sum of the even numbers in that range is 60.

There are 25 prime numbers less than 100 is their sum even or odd?
Oh, what a happy little question! Let's take a look at those prime numbers. When we add them up, we find that their sum is actually even. Isn't that just a delightful surprise? Remember, in the world of numbers, there's always a little bit of magic waiting to be discovered.
What is the sum of all even numbers less than 20?
The even numbers less than 20 are 2, 4, 6, 8, 10, 12, 14, 16, and 18. To find the sum, you can use the formula for the sum of an arithmetic series: ( n/2 \times (first\ term + last\ term) ). Here, there are 9 even numbers, so the sum is ( 9/2 \times (2 + 18) = 9/2 \times 20 = 90 ). Thus, the sum of all even numbers less than 20 is 90.

The difference of two numbers is always less than the sum of those two numbers?
The statement is true for all real numbers. Mathematically, if we have two numbers ( a ) and ( b ), the difference ( |a - b| ) is always less than the sum ( a + b ) when both numbers are positive. Even when considering negative numbers, the absolute value of the difference remains less than the sum. Thus, this relationship holds universally in the realm of real numbers.
