Use rounding to estimate the answer to each question.
1. If you add 98 to the difference of 71 and 56, what will result?
2 What difference will you get if you subtract 345 from the sum of 496 and 193?
3 Subtract 249,891 from 546,213. What is the difference?
4. Add 346,721 to the difference of 692 and 312. What number will result?
5. Subtract the difference of 543 and 182 from their sum. What will you get?

Answer:
1. 98 + (71 - 56) = 113
—> 100 + (70 - 60) = 110
2. (496 + 193) - 345 = 344 [but the correct estimated here should be 300 only]
—> (500 + 200) - 300 = 400
3. 546,213 - 249,891 = 296,322
—> 500,000 - 200,000 = 300,000
4. 346,721 + (692 - 312) = 347,101 [but the correcr estimated here here should be 300,00]
—> 300,000 + (700 - 300) = 300,400
5. (543 + 182) - (543 - 182) = 364
—> (500 + 200) - (500 - 200) = 400
I rounded it off to the highest place value.
