Answer 2

To solve the expression, let's first simplify the part inside the parentheses:

(2 - 1.8) = 0.2

Now, we have:

2,9 • 0.2

To perform the multiplication, we can set it up in a vertical format:

    2,9
x   0,2
------

Now, let's perform the multiplication as we would with regular whole numbers:

sqlCopy code
      2,9
x    0,2
------
      58   (0.2 * 9)
+    580   (0.2 * 9 * 10, shifted one place to the left)
------
      0,58  (Sum of the results, shifted two places to the left)

So, the result of (2 - 1,8) • 2 is 0,58.
