Here’s a brief summary of the terms you provided:

  1. Integer: An integer is any whole number, including both positive and negative numbers, as well as zero. This means integers encompass the set {..., -3, -2, -1, 0, 1, 2, 3, ...}.

  2. Number Line: A number line is a visual representation that displays all real numbers in a straight line, with equal intervals between numbers. It helps to illustrate the relative positions of integers, fractions, and other real numbers.

  3. Opposite: The opposite of a number is a value that is the same distance from zero on the number line but in the opposite direction. For example, the opposite of 3 is -3, and the opposite of -5 is 5.

  4. Whole Number: Whole numbers are the set of non-negative numbers that includes zero and all the positive counting numbers: {0, 1, 2, 3, ...}. Whole numbers do not include negative numbers or fractions.
