Opposites have the same absolute value since they are both at the same distance from 0.
If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. This distance between a number x and 0 is called a number's absolute value. You notice that all integers, as well as all rational numbers, are at a specific distance from 0. It is a rational number because it can be written as:Ī rational number written in a decimal form can either be terminating as in:Īll rational numbers belong to the real numbers. As it can be written without a decimal component it belongs to the integers. The number 4 is an integer as well as a rational number. 0, 2, 99 0, 3, 25 0, 4, 90 0, 1, 75 Model Whole Numbers In the following exercises, model each number using base-10 blocks and then show its value using place value notation.
…-4, -3, -2, -1, 0,1, 2, 3, 4,…Īll integers belong to the rational numbers. Identify Counting Numbers and Whole Numbers In the following exercises, determine which of the following numbers are (a) counting numbers (b) whole numbers. Integers include all whole numbers and their negative counterpart e.g. Whole numbers are all natural numbers including 0 e.g.

When using numbers to count how many elements a set has, it is referred to as cardinal numbers. The numeral that we use to represent the set above is 4 We write the number down using a symbol and we call the symbol a numeral. A number is an idea that we use to represent that quantity.
