In the equation

In the document, the formula is written as:

11 × 60^2 + 23 × 60^1 + 13 × 10^0 = 39,889_10

1- Since it is in Base 60, why is there a "10^0" in the last position?
2- If my calculations are correct, the total should be 40,993

Unless I misunderstood the whole thing, of course.

Thanks

In Figure 2-7

Hello

On the last line of Figure 2-7, the symbols in the Chinese column translates to "4 + 5 + 1,000,000" which makes the total 45,000,000 not 4,500,000. Again, unless I am mistaken.

Thanks

Hello

In the list of integers, there is a minus sign missing before the first number "2".

Thank you

Second paragraph below Table 2-3

Hello

In the first sentence. it is mentioned that "5 megabits means 5,000 bits". I think it should be 5,000,000 bits since mega = 1,000,000.

Thank you

On the 8th line of the second section of code

Hello

I think that there is an unnecessary closing parentheses after the curly bracket.

Thanks
