Include , Exclude and No Tax Rule

I like to learn erpnext about Taxes rule
here is the tax rule condition
Include Tax means the price that inputed on item price is summary of Actual price + 10% tax
Exclude Tax means the price that inputed on item price is Actual price + 10% and both displayed separately
for example
the price is 110,000
so when I used Include Tax the total should displayed 100,000 + 10,000 = 110,000
but when I used exclude Tax the total should displayed 110,000 + 11,000 = 121,000

where I can input this rule? and how I should input this rule ?
