That's the chemical equation for photosynthesis, not a mathematical equation. Here's what it means:

* 6CO2: Six molecules of carbon dioxide (CO2)

* 6H2O: Six molecules of water (H2O)

* C6H12O6: One molecule of glucose (sugar)

* 6O2: Six molecules of oxygen (O2)

The equation shows that:

* In the presence of sunlight and chlorophyll, plants use carbon dioxide and water to produce glucose (a simple sugar) and oxygen.

It's important to understand that this is a balanced chemical equation, meaning:

* The number of atoms of each element on the left side of the equation (reactants) equals the number of atoms of that element on the right side of the equation (products).

This ensures that matter is conserved during the chemical reaction.
