1) Integers: whole numbers that do not include decimals or fractions (ex. -1, 0, 1)
2) Positive Integers: whole numbers that are positive (ex. 1, 2, 3, 4, 5, 6…)
3) Negative Integers: whole numbers that are negative (ex. -1, -2, -3, -4, -5, -6…)
4) Zero: an integer that is neither positive nor negative
5) Consecutive Integers: integers that go in a row, in units of 1 (ex. 97, 98, 99, 100)

TIP FOR INTEGER AND CONSECUTIVE INTEGER PROBLEMS

Remember that, if the problem does not specifically refer to positive or negative integers, then zero must be included as an integer.

This is so important and such a common mistake, it's worth reading twice:

Remember that, if the problem does not specifically refer to positive or negative integers, then zero must be included as an integer.

SAMPLE PRACTICE QUESTION FOR CONSECUTIVE INTEGERS

The sum of 3 consecutive integers is 1,200. What is the value of the largest of these integers?

     Solution 1
     3 consecutive integers = x, x + 1, x + 2
     x + x + 1 + x + 2 = 1,200
     3x = 1,197
     x = 399
     So the largest integer = x + 2 = 399 + 2 = 401

     Solution 2
     3 consecutive integers = ___, ___, ___
     average = [ ___, 400, ___ ]
     largest integer = [ 399, 400, 401 ] = 401
