7,332 PointsShe's talking about binary numbers. each column in a binary number represents a power of two. So for an eight-bit byte, the columns would represent 128, 64, 32, 16, 8, 4, 2, and 1 in base-10. You get the total by multiplying those column values with corresponding values in the byte and adding the total. For example:
01010101 = 128*0 + 64*1 + 32*0 + 16*1 + 8*0 + 4*1 + 2*0 + 1*1 = 0 + 64 + 0 + 16 + 0 + 4 + 0 + 1 = 85.
and
10101010 = 128*1 + 64*0 + 32*1 + 16*0 + 8*1 + 4*0 + 2*1 + 1*0 = 128 + 0 + 32 + 0 + 8 + 0 + 2 + 0 = 170.
