Advantage of Base - n system:
There are two advantages in Base -n system
i) Addition of base -n system
ii) Multiplication of base -n system
Examples:
Question 1:
Solution:
Table value of Egyptian number system:
Regrouping the number of 
and 
we get,
and we get,\(15\) and \(15\)
and \(15\) From the above table we get,
\(= 10\) \( = 1\)From the table we get,
\(10\) \(=\) 
\(=\) \(10\) \(=\)
\(=\) Thus we get,
\(15\) \(= (10 \) \(+\) \(5\)
\(= (10 \) \(+\) \(5\) \(=\) ------ (1)
------ (1)\(= (10 + 5 ) \times 10\)
\( = (10 \times 10) + (5 \times 10)\)
\(15\) \(= (10 \) \(+\) \(5\)
\(= (10 \) \(+\) \(5\) \(=\) ------ (2)
------ (2)Thus the sum of (1) and (2)
\(=\)
Question 2:
Find the product of the following:
Solution:
From the table we get,
\(=10\) \(=10 \times 10\)\(=10^{2}\)
\(=\)
In a similar way, we can also do some arithmetic operations on Mayan and Roman numbers.
Difficulties in doing simple calculations in non decimals number:
1. No place values for Egyptian and Roman number system
2. No symbol for zero in Egyptian and Roman number system
3. While creating lengthly or complimented representation of numbers it will lead to errors.
4. It does not have standard algorithms for arithmetic operations
5. There were some difficulties while doing multiplications and divisions
6. It would be harder to do (time consuming) simple operations in symbols instead of decimals
7. The mayan number has a base of almost \(20\), instead of base - \(10\), which it have it own difficulties while working out.
