The number 143 in binary is the eight-digit number 10001111.

The digits in a binary number are exponents of 2 rather than 10, so that for an eight-digit number in binary, the digit places represent

128, 64, 32, 16, 8, 4, 2, 1 instead of increasing values of 10.

10001111 = 128 + (0x64) + (0x32) + (0x16) + 8 + 4 + 2 + 1 = 143
