【Do you know an almighty pair of scales?】

《A question in which a sense of mathematical is necessary for us》　

Then we think it of with quaternary in which number from 1 to 3 in every digit. When trying to express 13 with the quaternary, it’s 31. Why?

Its numerical equation is 3×4＋1×0＝13

When trying to express with English, 3 multiplied by four to the first power plus 1 multiplied by four to the 0th power, then three means three weight is used. Then 1 is 4 to the 0th power, it means a single weight is used. It’s 31, so 13 is equal to 31 when changing from the decimal system to quaternary.
