Detail #1 It's easy to use & some people might not yet know it, because it is easier to read & each number has a value. Detail #2 You cannot do the Place Value with Roman Numeral System. It's important to know the value of numbers. Detail #3 Drawing Roman Numerals could use up more pencil lead, so we should use Base-10 number system so we don't use more pencil lead. Why we should keep the Base-10 Closing Concluding Sentence There are many ways to show us that we should keep the Base-10 number system, In my estimate, there's hundreds of ways, but I can only list some of them. For example... Place Value You cannot do the Place Value with the Roman Numeral System. The Base-10 Number System is the only number system that uses the Place Value. Romans never used that in their system. The Difference Can you tell the difference between Base-10 & Roman Numerals? The Base-10 Number system has 10 symbols, 1, 2, 3, 4, 5, 6, 7, 8, 9, & 0. The Roman Numeral System uses only 7 symbols, while some of those symbols are used rarely, they are, I, V, X, L, C, D, & M. "M" is really used rarely. How old is the Roman Numeral system? It's been used since the ancient times!

More than 2,000 years ago! If young kids use this, they would be confused! That's some reason we need Base-10! I don't how old Base-10 is, but I bet all students should learn the Base-10 by the time they're in 1st Grade, & Roman Numerals by the time they're in middle school. Patterns They Repeat! They Grow! The Base-10 Number System is the only number system that ever used growing & repeating patterns. Look at these examples. 6, 13, 20, 6, 13, 20 Repeating Pattern Growing Pattern 5, 10, 15, 20, 25, 30 (etc.) The Truth is... Romans use the Roman Numeral system because that is how Romans use numbers.

Americans use the Base-10 because that is how we use numbers.

We need to keep how use normally & usually use numbers. State Opinion Why we should keep the Base-10 Written by Daniel Dorrian Problem Solving We need mathematics problems! If you try to solve problems with the Roman Numeral System it won't work! We need the Base-Ten Number System!!!!

In America, we need the Base-Ten Number System more importantly! Please don't delete the Base-Ten!
