That's not how hexadecimal works. You can't just multiply the hexadecimal digits together and get an answer in decimal.
Think about how numbers work in decimal (base 10) first. A number like 753 can be written as:
7 ×?100 + 5 ×?10 + 3 ×?1
In other words:
7(102) + 5(101) + 1(10?)
Each digit in decimal represents the next power of 10 up. The '7' in 753 really represents 700 = 7(102).
Now, hexadecimal uses base 16 instead of base 10. Therefore, you can write a number like 2F1 as:
2(162) + F(161) + 1(16?)
= 2(256) + 15(16) + 1(1)
= 753 (base 10)
Each digit in hexadecimal represents the next power of 16 up. The 2 in 2F1 really represents 512 = 2(162).
For base 10:
1000 100 10 1
For base 3:
27 9 3 1
For base 4:
64 16 4 1
For base 2"
8 4 2 1
Each base has it's placeholder multiplied by the base as shown above. So how would we do this for base 16?
16x16x16....16x16....16....1
....4096.........256......16....1
......................2.........F....1 = 256x2 + 16x15 + 1 = 512 + 240 + 1 = 753
2F1 = 2*16^2+ 15*16^1 +1 *16^0 = 753
2 * 16^2 + 'f' * 16 + 3 =
2*256 + 15*16 + 3 = 755
yes youre confused
234 decimal is NOT 2*3 *4,
it's 2 * 100 + 3 * 10 + 4
hex works similarly.
why to the power of 2 and 1 please xplain
how could 2F1=753, 2x15x1 is only 31
