Answer 2

To solve this expression step by step and write it out vertically, you can use the following format:

diffCopy code
  9 * 2.1
+ 5.9 * 0.26
- 0.3 * 1.33

Now, calculate each line:

1. 9 * 2.1 = 18.9
2. 5.9 * 0.26 = 1.534
3. 0.3 * 1.33 = 0.399

Now, subtract the third result from the sum of the first two results:

diffCopy code
18.9
+ 1.534
- 0.399

Now, add the first two results and subtract the third:

diffCopy code
18.9 + 1.534 = 20.434
- 0.399 = 20.035

So, the final result is 20.035.
