## starter hydration maths question.

i have worked through all the maths lessons and i still seem to have a problem

where the maths of starters / sponges / poolish / biga are concerned.

here is what i mean.

i take 10g of starter @60%

so how much is flour and how much is water?

i add 20g water and 20g flour.

total weight is now 50g.

what it the hydration now?

i add a further 6g of water and 24g of flour.

total weight is now 80g.

what it the hydration now?

what i need to see is how much water and flour is totaled up for each calculation.
