How many of you know multiplication tables from 1 to 20 by heart?
What about you?

One more hint for you :ConquerorHex and stuff with math I am game I love it and tricks I am in, do reveal it here mate

Why not up to 15 😲, table of 15 is easiest one between 12-19 😛.shailaja revathiI rememeber tables from 1-14 .(and while teaching my younger brother I brag that I know till 25😛 ).
Not sure which trick you are talking about.Abhishek RawalCan you remember addition of two single digit hex number ?
I have a trick for that 😁
Example: convert a each hex into individual binary in 4 digit of binary. and club them. like: C4 = 11000100 will be C=1100 and 4 = 0100 and vice versa for binary to hex.

Surely I'll try .Well thanks for the trick(atleast idea :something is better than nothing😁 )Abhishek RawalLet's not make it easy as pie :
Jot down all single digit hex addition in one piece of paper.
You'll understand it's pattern.
Start memorizing.
Hint : Trick is available somewhere in corner of internet.

Actually I remember 15's table only upto 5 or 6 and after that I start inventing my own maths.😁ianoopWhy not up to 15 😲, table of 15 is easiest one between 12-19 😛.

Too long, too easy & too damn elementary, buddy.nareshkumar6539We know single digit hex number in decimal number
Eg: For 'A' equivalent decimal number is 10
First convert those single digit hexa number into Decimal then add
if the resultant sum is less than or equal to 15 result it self is the sum.
If the resultant sum(lets say sum) is greater than 15 then
SUM (2 digit number) is Quotient(sum/16)Remainder(sum%16)
Example:
1) adding 4 and 5 hexa decimal numbers sum is 9
2)adding 'A' and 'F' hexa decimal number Sum is 19
Decimal equivalent of A is 10 and decimal equivalent of 'F' is 15 add those
result is 25 it is greater than 15 so
When we divide 25 with 16 then Quotient is 1 that is first digit in sum and remainder(9) is second digit in SUM
SUM('A'+'F') is 19 in Hexa decimal number

rahul69I tried to create one, here is it:
For understanding it, let us take an example:
- Add the decimal equivalents of two single digit hex numbers
- If result less than 16 then it's hex equivalent is the answer, else subract it by 6
- If result after above step is less than 20 then it is the answer, else write it as : 2n --> 1(1n), convert 1n to hex, and we get the result.
Suppose we have to add E and A.
Now adding their decimal equivalents,we get: 14+10=24
As 24>15 apply rule 2, ie subtract 6 : 24-6=18
as 18<20 Hence 18 is the answer, ie E+A = 18

Nope, I am doing single digit hex addition, maybe that 6 confused you, as we add 6 in BCD addition, but I am subtracting 6, and it is totally a different story 😁Nayan GoenkaAre you trying to do BCD addition?
