Computing and Computer Science resources for GCSE, A-Level, and IB.
Computer Science denary, hexadecimal, binary number line class display
Binary number line for classroom displays, suitable for GCSE, A-Level, or IB Computer Science. Download includes:
Binary, hex, and denary values from 0 to 20
Binary and denary values from 0 to -20 (sign and magnitude)
Binary and denary values from 0 to -20(two’s complement)
