Question

1. when subtracting 537 - 443, why is there no digit in the hundreds place?

Explanation:

Step1: Subtract hundreds place (with borrow)

First, we need to borrow 1 from the hundreds place for the tens place subtraction: originally, tens place is 3 - 4, which requires borrowing. So the 5 in hundreds place becomes 4. Now subtract hundreds digits: $4 - 4 = 0$.

Step2: Explain leading zero rule

In standard whole number notation, leading zeros (the zero in the hundreds place here) are not written because they do not change the value of the number.

Answer:

After borrowing 1 from the hundreds place to complete the tens place subtraction, the hundreds place calculation becomes $4 - 4 = 0$. Leading zeros in whole numbers are not written, so there is no digit shown in the hundreds place of the final result. The result of $537 - 443 = 94$, which has no hundreds place digit because the hundreds place value is 0.
