二進制數教我怎樣做?

1x16+1x64+2
=1x(2^6)+1x(2^4)+1x(2^1)
=1x(2^6)+=0x(2^5)+1x(2^4)+=0x(2^3)+0x(2^2)+1x(2^1)+0x(2^0)
=1010010(2進制)

u can also use calculator to work or to prove work*
a botton'BIN' = 2進制-
'DEC'= 10進制-
'HEC'= 16進制-
'OCT'= 8進制-

1: 入no. e.g. 0
2: 按BIN
3: mon出現0個個就係2進制既ans.

(ps.不同caltor有不同用法-本人是用sharp)
