1,50-2-1,52

It seems you have provided a sequence of numbers with subtraction operations between them. To solve this expression, simply follow the order of operations from left to right, as there are no parentheses or exponents present:

1.50 - 2 - 1.52

Since subtraction is performed from left to right, we start with the first two numbers:

1. Start with 1.50 - 2 = -0.50 (you owe 0.50 if you had 1.50 and spent 2)

Now take this result and subtract the last number:

2. Then take -0.50 - 1.52 = -2.02 (now you're further in debt by an additional 1.52, for a total debt of 2.02)

So the result is -2.02.
