1,50-2-1,52

It looks like you're trying to perform a subtraction problem with decimals. To solve this, we'll line up the decimals and subtract one by one, just like we would with whole numbers.

Here is the subtraction laid out:

 1.50
-2.00
-1.52

First, we subtract 2.00 from 1.50:

 1.50
-2.00
------
-0.50

So now we have -0.50 (negative because 2.00 is greater than 1.50). Next, we subtract 1.52 from -0.50. When subtracting a larger number from a smaller one, the result will be negative. We can think of it as -0.50 minus 1.52:

-0.50
-1.52
-----
-2.02

So the answer is -2.02.
