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’s left columns to convert the left side LEDs into the base number.
- The display in 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 1’s right columns 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 2 to determine the adder/subtractor/multiplier/divider.
- Perform the action required and use Table 3 to convert the answer into colors, then input it on right side LEDs. Push SUBMIT to check.
