Standard reduction potentials

I am confused. Why is that when you multiply to balance half reactions, you don't multiply the E?

you don't multiply the value of the e cell because the E represents the cell's potential under standard conditions being at
25 C, 1 atm, and one mole and so even if you multiply and change the amount of moles, the value of the e cell would still wouldn't change and this isn't like hess's law where you can add and multiply everything.

E is an intensive property, so it stays the same regardless of if you multiply the whole equation or divide the whole equation. The voltage does not depend on how many times the reaction occurs.
