Hex and decimal conversion

In computing and network field, we should know at least four types of numeral systems. A numeral or number system is a way to represent numbers. We use the base-10 system, or decimal on a daily basis. Other three common numeral systems include base-2 binary, base-16 hex, or hexadecimal, and base-8 octal, or oct.

Thank you so much your best ! You helped me in networking and now computer logic

How do you get the remains at the conversion of decimal to hexadecimal?

[@HenryBuild-sp6or]

472/16 - the remainder is 8 ???? How ???

[@7Ventus7]

Mikalai Yavorski if you divide 472 by 16 you get 29, something, but now multiply 29 by 16 and you get 464. Now you have 472-464=8.

[@7Ventus7]

Hope i could help you with this answer :)

[@davidb1132]

472/16=29 remainder 8. 29/16=1 remainder of 13. 1/16=0 remainder of 1. So from bottom up, 1 13 8 in hex 1 D 8. To confirm, multiply the hex by their corresponding power; 16 to the power of 2 (256*1=256),16 to the power 1 (16*13=208) and 16 to the power of 0 (1*8=8). Add them up and you get 472 again

[@limjunying1927]

​@@HenryBuild-sp6or 472/16 = 29.5
then you multiply the decimals with 16
16 x 0.5 = 8 and you get the remainder
same goes for 7562.
7562/16 = 472.625
0.625 x 16 = 10
hope this helps the people who start watching it in 2021.

for the first one i do not understand how you got 34 when i divide 16/22 i get 1 w/ a remainder of 6 then a remainder of 1 which would be (16) in hex hopefully you find yourself well, hope to hear from you soon :) thank you for your videos.

[@davidb1132]

Martin Pantoja (22) base 16 or hexadecimal. This would be 16 to the first power and 16 to the 0 power. 2*16=32 and 2*1=2. So 32+2=34

[@codewithdevhindi9937]

thank you sir

Thank you

What animation software do you use for the chalkboard animation?

[@sunnyclassroom24]

old flash software with green board pic as background.

[@jasonluong3862]

I am sorry to say that Flash is being phased out in favor of newer technology. I want to do presentations like the way you do it with the blackboard. Can you recommend a different software that is not Flash that can export non-Flash videos?

at step 0.625x16=10,0.5x16=8 the remainder multiplied by 16
