Calculated Answer

Step by Step Solution

In order to solve problem, you must evaluate 100 - (n₀ + n₁ - n₂).

n₀ =	20
n₁ =	70
n₂ =	10

100 - (n₀ + n₁ - n₂)
Evaluate n₀ + n₁ = 90
100 - (90 - n₂)
Evaluate 90 - n₂ = 80
100 - 80
Evaluate 100 - 80 = 20
20
The answer to the problem and the result of 100 - (n₀ + n₁ - n₂) is 20
