What is \(6.3 + 0.47\)?
Line up the decimal points: \(6.30 + 0.47 = 6.77\).
Practice 9Quick check
Which addition checks the answer to \(1{,}000 - 386 = 614\)?
The answer plus the number you subtracted should give back the starting number: \(614 + 386 = 1{,}000\).
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
