Base Conversions Method 1. (Any Base Base 10). 1) Check the number for validity; each digit should be less than the base. . e.g. 102 4 is valid since each digit is less than the base. But 153 5 is invalid; 5 is not less than the base.

Base ConversionsMethod 1 (Any Base Base 10)
1) Check the number for validity; each digit should be less than the base.
e.g. 1024 is valid since each digit is less than the base. But 1535 is invalid; 5 is not less than the base.
The person who started with this number was most likely checking work done with method 2, since method 1 is used to check method 2.
2) Determine the positional value for each digit. Starting with the rightmost position, give it a value of 1 (base to the zero power).
To determine the preceding positional values, multiply the current positional value by the base e.g. 3859 3 8 5 base 9 | | | 81 9 1
3) Then multiply each digit by its positional valuee.g. 3 x 81 = 243 8 x 9 = 72 5 x 1 = 5
3 x 81 = 243 8 x 9 = 72 5 x 1 = 54) and add them together ==== 320 this is the answer in base 10
5) Finally, check the result for validity; each digit should be less than 10. (If it is not, then you did something wrong and should start over)
