Calculate the Sum: 0 + 0.2 + 0.6 Using Decimal Addition

Both methods work for addition! Left-to-right helps you break the problem into smaller steps: first $0 + 0.2 = 0.2$, then $0.2 + 0.6 = 0.8$. This makes it easier to track your work.

Adding zero to any number doesn't change that number! So $0 + 0.2 = 0.2$. Zero is the additive identity, meaning it has no effect on addition.

Always line up the decimal points vertically when adding. In $0.2 + 0.6$, both decimals have one place after the point, so your answer will too: 0.8.

Yes! Addition is commutative, so $0 + 0.2 + 0.6$ equals $0.6 + 0.2 + 0$. You'll always get 0.8 no matter what order you choose.

Your answer would be completely wrong! Writing 8 instead of 0.8 makes your result 10 times bigger than it should be. Always double-check that your decimal point is included.
