On the Subject of Color Math

So many colors!

  • This module contains 2 rows of LEDs, left (represents the base number) and right (represents adder/subtractor/multiplier/divider and/or answer).
  • Numbers in this module are ranged from 0-9999 inclusive. LEDs are read from the top (Most Significant Digit) to bottom (Least Significant Digit).
  • Use Table 1 to convert left side LEDs into the base number.
  • The display at the middle of this module shows the action that needs to be performed: [A]dd / [S]ubtract / [M]ultiply / [D]ivide.
  • If the text in the display is GREEN, use Table 2 to convert right side LEDs into the adder/subtractor/multiplier/divider.
  • If the text in the display is RED, ignore right side LEDS and then use Table 3 to determine the adder/subtractor/multiplier/divider.
  • Perform the action required and use table 4 to convert the answer into colors, then input it on right side LEDs. Push SUBMIT to check.

  • Note: On the subtraction, if the answer is negative, answer as positive.
  • Note: On the division, if the answer contains remainder, ignore the remainder.
  • Note: If the answer exceeded 9999, please divide the answer with 10000 and answer with the remainder. (Or in short, modulo it with 10000.)
