Final answer:
Cardinal numbers indicate quantity and are made up of digits 0-9. Examples include 1, 2, 3, 4, 5, and 6. These concepts are key in mathematical concepts like scientific notation and significant figures.
Step-by-step explanation:
Cardinal numbers are numbers that represent quantity. For example, if we say there are six apples, the word 'six' describes the number of apples. Here are six examples of cardinal numbers:
- 1
- 2
- 3
- 4
- 5
- 6
Each number represents a count of objects or units. Numbers are composed of digits, which are 0 through 9. When these digits are arranged in a sequence, they form numbers, such as 123, which is read as one hundred and twenty-three.In tasks like expressing numbers in scientific notation or identifying significant figures, understanding the concept of cardinal numbers is fundamental. For instance, the number 6 can be expressed in scientific notation as 6., implying a decimal point to its right making it eligible for conversion if needed. The significance of digits also plays a crucial role, such as in the case where '5', '2', and '9' are significant according to certain rules of significant figures.
