Calculated Answer

Step by Step Solution

In order to solve problem, you must evaluate n₀ + n₁ - n₂ - n₁.

n₀ =	50
n₁ =	12
n₂ =	22

n₀ + n₁ - n₂ - n₁
Evaluate n₀ + n₁ = 62
62 - n₂ - n₁
Evaluate 62 - n₂ = 40
40 - n₁
Evaluate 40 - n₁ = 28
28
The answer to the problem and the result of n₀ + n₁ - n₂ - n₁ is 28
