I'm gonna take a stab at this from the example I found referencing the notation. It seems that the operands are all considered binary expressions; therefore, in context, what you're looking at is a string of individual number values. That makes the 42 and 56 two sets of two integers each. The first set of two consists of the numerical values 4 and 2 rather than components of the expression forty-two. The same goes for the next set of integers, 5 and 6, which should not be construed as anything like 56.
The sequence in which the operators are to be applied to the individual operands relies upon proximity. The equations, as written, are + / 4 2 + 5 6 ... In this type of notation, the operators are put ahead of the operands. That is, the action to take is put ahead of the things acted upon. This means that what is closest to being resolvable gets evaluated first. What is seen of what's written, when observed closely, is + 5 6.
This means add 5 and 6. The result is 11. The expression then looks like this:
+ / 4 2 11...
The next decipherable equation that you can see is / 4 2... That means divide 4 by 2. You are now left with an equation that looks like this: + 2 11... This is the last expression to be seen in the lot, and just means "add two to …
