Question

For what value of n is (n - 1)+1 equal to zero?

Answer 1

n=1/2

Explanation:

(n-1)+1=0

Remove unnecessary parenthesis

n-1+1=0

Collect like terms

2n-1=0

move the constant right-hand side and changes its sign

2n=1

Divide both sides of the equation by 2

n=1/2

Answer 2

When n = 0

Explanation:

n - 1 + 1 = 0

→ Simplify

n - 0 = 0

→ Add 0 to both sides

n = 0
