Thousand as a Unit
As we have learnt how to count in hundreds and also about thousand as a unit, here, we shall continue to count through to ten thousand. One thing we should take note of is that 999 + 1= 1,000 (one thousand). This is written with a comma, separating the thousands unit = 1, 000 Note that 10 ones = 1 Ten.
Note:
Therefore: 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 = 1, 000
