CHALLENGE: Use front-end estimation with adjustment to estimate the sum.
1,963 + 3,290 + 7,837
= 13,000
(1,963 + 3,290 + 7,837
Use the first digits: 1,000 + 3,000 + 7,000 = 11,000
Use the second digits: 900 + 200 + 800 = 1,900
Round 1,900 to the nearest thousand: 2,000
Add the values: 11,000 + 2,000 = 13,000)
