This episode proceeds our discussion on the Basics of Digitizing Data. In bespeak to understand how computer systems work, first, you have to go back to your simple math. Let’s talk around the icons we usage to represent quantities. This illustration is a quick overview of ours counting system and also Base-10 numbering system.
You are watching: A symbol used to represent a number
Your an essential takeaways are:
Numbers and also digits room the symbols supplied to represent a quantityDigits space the numbers 0 come 9The Decimal Number device is based upon the amounts of 10Base-10 is expressed as 10 to the power of a aspect of XStudy Notes
How do we represent the variety of items?
Numbers space symbols which represent a count or quantity. We space putting focus on “symbol” and also “representation.” Humankind produced “numbers” together a kind of global language.

What is the number pattern?



You deserve to break this down right into patterns:
How plenty of times perform you count 10 on your fingers? 2 times, or 2 counts that 10 clocks.What is remaining? there is 1 clock remaining.Now stop formulate a mathematics expression.2 counts that 10 is the very same as 2 x 10.1 remaining is the same as 1 x 1.We have a certain number of items. Below these items are clocks.We want to determine the amount of clocks by counting them.Show just how a decimal number is a symbol provided to represent the amount of something. Here, the symbols are clocks.Then, we begin breaking it down into positional notation.Convert that into base-10.If we have actually 2 x 10 then we can say that there room 2 tens.Using Base-10, “tens” is represented by 10 to the power of 1, as that amounts to 10.Therefore, we deserve to say 2 x 101 which equates to 20.If we have 1 x 1, then we can say there room 1 ones.Using Base-10, “ones” is represented by 10 to the strength of 0, together that equals 1.Therefore, we have the right to say 1 x 100 which amounts to 1.We just created a symbol set to represent 21 clocks.Decimal Number mechanism Base-10
