How do you introduce a decimal place value?
How do you introduce a decimal place value?
The place value in decimals is based on preceding exponential of 10. When shifting from the left to the right of a decimal number, the integers get divided by powers of 10 (10 -1= 1/10, 10 -2 =1/100, 10 -3= 1/1000, etc.), implying that, the decimal place value defines the tenths, hundredths and so on.
What is the importance of place value and decimals?
Understanding place value is important because it helps you understand the magnitude of numbers. Because of place value we know 30 is 10 times bigger than 3 which is a hundred times bigger than 0.03. This would not have been possible with Roman Numerals as they do not have a decimal point, or zero for that matter.
