Question

the number line shows an unknown number, u.
is 1 + u positive or negative?
positive
negative
submit

Explanation:

Step1: Analyze the number line

From the number line, we can see that \( u \) is between \( 0 \) and \( 1 \), so \( 0 < u < 1 \).

Step2: Determine the sign of \( 1 + u \)

We know that \( 1 \) is positive and \( u \) is positive (since \( 0 < u < 1 \)). The sum of two positive numbers is positive. So \( 1+u>0 \), which means \( 1 + u \) is positive.

Answer:

positive
