Prefix order
Okay kiddo, let me explain what prefix order means. Prefix order is a way of writing mathematical formulas or expressions so that the operator (like plus or minus) comes before the numbers or variables it's operating on.
Let's say you have the math problem "2 + 3 * 4". In prefix order, we would write it like this: "+ 2 * 3 4".
The plus sign comes first, followed by the two numbers it's adding together (2 and whatever the result of multiplying 3 and 4 is).
So when we read this expression, we start with the plus sign and then move on to the numbers that it's operating on.
This way of writing expressions is helpful because it makes it very clear which operator comes first, and it avoids any confusion about the order of operations.
Does that make sense, kiddo?
