What about 1.2 – 0.21 = 0.99?

“1.2 – 0.21 = 0.99” has two 9’s.

1.9 – .9= 1

There are two nines and you can’t use zeros

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

1.2 -0.21 = 0.99

This is my corrected answer : 1.6 – 0.58 = 1.02

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

1.9-9

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!

I put 1.2 – 0.21 =0.99

1.3-0.42=0.88

1.5 – .49

1.7- 0.7

3.9-2.9

1.30-0.30

1.6 – 0.58 = 1.02
