The Roman Numeral, as far as we know, was the only written numbering system used in Ancient Rome andEurope until about 900 AD, when the Arabic Numbering System, which was originated by the Hindu's, came into use.
Answer:
10,000
Step-by-step explanation:
9564
9=thousands
5=hundreds
6=tens
4=ones
the number behind the thousands (5) must be 5 or higher to be able to round up. Because the number in the hundreds place is 5, the 9 can round up to 10, making it ten thousand (10,000).
Rules for adding: if the bases are the same you can add them, and subtracting happens in a fraction
25 because $518 ( their total ) divided by $21 ( the amount for EACH uniform) is 24.6 which isn’t possible so round it to 25
