Answer: Two values are 369600 and 300000.

Step-by-step explanation:

If we rounding the integers to nearest ones ,

$1537 \text{change into }1540\\\\242\text{ change into }240\\\\So,\\\text{Sum will be }\\=1540\times 240\\=369600$

If we rounding the integers to nearest tens,

$1537\text{ changes to }1500\\242\text{ changes to }200\\So,\\\text{Sum will be }\\=1500\times 200\\=300000$

Hence, by estimation, we get

Two values from above two cases are 369600 and 300000.

It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954
