Question

round 4,158 to the nearest thousand.

Explanation:

Step1: Identify the thousands place

In 4,158, the digit in the thousands place is 4, and the digit to the right (hundreds place) is 1.

Step2: Apply rounding rule

Since the digit in the hundreds place (1) is less than 5, we round down. So we keep the thousands digit as it is and change the remaining digits to zero.
