1. What about 1.2 – 0.21 = 0.99?

• Never telling my name.

“1.2 – 0.21 = 0.99” has two 9’s.

2. • There are two nines and you can’t use zeros

3. 1.1-0.09=1.01
1-0.02=0.98

• In the first one there are two ones and for the second one you can’t use zeros

4. 1.2 -0.21 = 0.99

5. This is my corrected answer : 1.6 – 0.58 = 1.02

• Nice, but, why wouldn’t you use 0.59? Am I missing something?

6. 7. 1.2-0.34=0.86

1.30-0.24=1.06

1.90-0.87=1.03

My last drawing is my answer this was hard!

8. I put 1.2 – 0.21 =0.99

9. 1.3-0.42=0.88

10. 1.5 – .49

11. 1.7- 0.7
3.9-2.9

12. 1.30-0.30

13. i aint telling my name
