In hexadecimal, "del" does not directly represent a numerical value, as it is a string of characters. However, if you consider each character's ASCII value, 'd' is 64 in decimal (or 0x64 in hexadecimal), 'e' is 101 in decimal (or 0x65 in hexadecimal), and 'l' is 108 in decimal (or 0x6C in hexadecimal). Therefore, the string "del" can be represented as a sequence of hexadecimal values: 0x64 0x65 0x6C.

Without context, it is difficult to say. I guess you are referring to number bases greater than 10 where letters are used to represent digits above 9; the first digit would be A, the second B and so on. In these cases the letter A is being used to represent 10 times the column value where it is. For example in hexadecimal, the A in 0x6A3 represents 10 x 16 = 160 in decimal (since it is in the sixteens column of the number).
