Multiplying by 10 and by 2 (doubling)
are both simple operations using the Egyptian number system:
Doubling
To double a number all you need to do is write the
number twice and then convert every ten of a symbol into one of the next higher
symbol.
Multiplying by 10
The Egyptian number system uses symbols to represent each of
the powers of 10 from 0 to 6. So to multiply a number by 10 simply
change each symbol to one of the next higher symbol:
236 x 10=
6 Units become 6 Tens
3
Tens become 3 Hundreds
2 Hundreds become 2 Thousands
=2 Thousand, 3
Hundred and 6 Tens (Sixty)
=2360 |
