Tally numeration systemThe tally numeration system is probably the simplest of all numeration systems ever used. It makes use of single strokes to represent object being counted. One stroke is used for each object The following shows how we can use stroke(s) to represent the count for 1, 2, or 3 squares  First, large number will require an aweful lots of strokes. Second, it will be somewhat difficult to real such large number For example, can you tell what number is represented by the tally marks below?  I know what you are doing right now. You are using your finger to count the strokes However, would you be able to do that without confusing yourself or losing your place if there were 50 strokes? If you did not lose your place, you must have counted 20 strokes However, the introduction of grouping made it a lot easier to read numbers In this case, we place a fifth tally mark across every four to make a group of 5 The number shown above will be represented as follow:  Basically, that is all there is to this numeration system.Today, this numeration system is used a lot in stastistics. Fun math game: Destroy numbered balls by adding to 10
