The hierarchy of operations works as follows:

First, operations in brackets, brackets or braces are resolved independently.

Next, the powers and roots are realized.

It continues to solve multiplications and divisions.

Finally, the addition and subtraction are carried out, regardless of the order.

6 x 0.9 + 0.1 / 4 -0.23 =

First, multiplications and divisions:

5.4 + 0.025 - 0.23.

Then, addition and subraction:
