### Example Question #2 : How To Add Integers

What is the sum of all of the *even* integers from 2 to 2,000, inclusive?

**Possible Answers:**

**Correct answer:**

Pair the numbers as follows:

...

There are 500 such pairs, so adding all of the even integers from 2 to 2,000 is the same as taking 2,002 as an addend 500 times. This can be rewritten as a multiplication.

### Example Question #122 : Integer Operations

Simplify

### Example Question #9 : How To Add Integers

Solve:

**Possible Answers:**

**Correct answer:**

To solve , first add the ones digit.

The ones digit is 4. Since 14 is ten or greater, carry the tens digit to the next number.

Add the tens digit with the one carried over.

The tens digit is 1. Since 11 is ten or greater, carry the tens digit to the next number. There are no hundreds digit with 98. Add both the thousands and hundreds digit to the carry over.

Combine this with the tens and ones digits.

The answer is:
