# Adding Multiple Decimals

Directions: Use the digits 0 to 9, at most one time each, to fill in the boxes so that the sum is as close to 10 as possible.

### Hint

How can we get close to one by adding digits in the ones place?

8.2 + 1.3 + 0.49
8.3 + 1.2 + 0.49
8.2 + 1.4 + 0.29
8.3 + 1.4 + 0.29

## Subtracting Multi-Decimals

Directions: Use the digits 1 to 9, at most one time each, to fill in …

1. thank you for the task. Please edit the name.

2. The directions say only digits 1 to 9. Please correct if you are using the digit zero (0). My solution was 5.6 + 1.4 + 2.98 using your allowed digits.

3. 5.7+1.8+2.49

My 6th graders said you could not use 0 in the directions 🙂

4. Here is the beauty of Open – middle: discussions about what you didn’t think about.

I think in the original problem you could replace the box for the numbers place with a zero.

OR you could allow zero to be used, then?
5.9 + 2.3 + 1.80 !
Technically my answer is incorrect because the original problem says “”…as close to…” not to actually reach 10, so: 6.9 + 2.3 + 0.81 ! (You didn’t say we couldn’t go over 10)

I’m sure there is more!
