Examples

This plant growth modifier changes carrots. Carrots will take 2x more time to grow if not under sunlight. Will take 1.5x more time to grow if in a cold biome. Will not grow if in Winter or Summer.
If it's in the correct season and the other modifiers are both applied, the formula is 2 + 1.5 = 3.5x more time to grow.
Instead, if in the wrong season and the other modifiers are both applied, the formula is 2 + 1.5 + ((2 + 1.5) * -1) = 3.5 + (3.5 * -1) = 3.5 - 3.5 = 0, so will not grow.
