academic math paper easy to read Product already exists Looks for sum extracts sums Take sum strings & evaluate
stored as strings
Whole Numbers: whole or decimals (3 places) Operators : + - * / Edge Cases are possible Output returned = An array of the output [sum string, outputted result (number)]
Input specification = There must be spaces between the number and operator
What we are looking for = "1 + 1" , ["1 + 1", 2]
Edge Cases =
- String spacing is wrong = "Input must be a valid mathematical string separated by spaces"
- String empty = "the string is empty you numpty"
- No Argument supplied = "Please supply an argument"
