Calculated Answer

76

Step by Step Solution

In order to solve problem, you must evaluate (n₁ + n₂) * (n₀ + 1) - n₀ * n₁.

n₀ =	10
n₁ =	32
n₂ =	4

(n₁ + n₂) * (n₀ + 1) - n₀ * n₁
Evaluate n₁ + n₂ = 36
36 * (n₀ + 1) - n₀ * n₁
Evaluate n₀ + 1 = 11
36 * 11 - n₀ * n₁
Evaluate 36 * 11 = 396
396 - n₀ * n₁
Evaluate n₀ * n₁ = 320
396 - 320
Evaluate 396 - 320 = 76
76
The answer to the problem and the result of (n₁ + n₂) * (n₀ + 1) - n₀ * n₁ is 76
