Question

half the input number z plus 1​

Answer 1

Answer:

$\underline\red\bf{z \: + \: 1 \: = \: z1}$

$\frac{1}{2 \:} \: of \: z1 \: = \frac{z1}{2}$

Answer 2

Here an expression is given as $z+1$

What if this expression is halved?

So in general we represent this expression as the same like $z+1$

Half the input number $z+1$ means dividing it by two,

So the expression after halving the number is, $\frac{z+1}{2}$ as we divide the expression by 2.

Half the input number $z+1$ is, $\frac{z+1}{2}$
