Calculating rules to be alright, worked around old mass (9)
I believe the answer is:
algorithm
'calculating rules to' is the definition.
I can't tell whether this definition defines the answer.
'alright worked around old mass' is the wordplay.
I cannot quite understand how this works, but
'around' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
an anagram of 'alright' is 'algrith' which is located in the remaining letters.
'mass' could be 'm' (symbol used in Physics e.g. f=ma) and 'm' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'be' is the link.
Can you help me to learn more?
(Other definitions for algorithm that I've seen before include "process" , "Step-by-step method for problem solving" , "Set of rules for solving problem by computer" , "Step-by-step solution method - oral might (anag)" , "Set of rules (for computer) to solve a problem" .)
