- numberBlue = wordBlue = ILLEGAL
- numberGreen = "Green" = FALSE
- wordRed = "Red" = FALSE
- wordBlue = "Blue" = FALSE
- numberRed <= numberGreen = TRUE
- numberBlue >= 200 = TRUE
- numberGreen >= numberRed + numberBlue = TRUE
- numberRed > numberBlue AND numberBlue < numberGreen = FALSE
- numberRed = 100 OR numberRed > numberBlue = TRUE
- numberGreen < 10 OR numberBlue > 10 = FALSE
- numberBlue = 30 AND numberGreen = 300 OR numberRed = 200 = FALSE
