Exactly what problem will this solve?: Not possible to make questions in the test tool, that involve numeric answers and calculations and allow correct answers within a certain range.
For whom do we solve that problem?: Teachers
How will we measure success?: Easier for especially math teachers and teachers in technical subjects to create test questions that require numeric answers and automatically calculates the correctness of the answer (range defined by the teacher himself).
What alternatives are out there?: NR
Why we are best suited to pursue this?: NR
Why now?: Long standing customer wish. Especially from technical schools.

User story:
As a: Teacher
I want to: be  able to easyily create test questions, that requires numeric answers and to define a range within which I accept answers.
so that: I can easily create such a question without myself having to write every accepted alternative to the 100 % correct answer (which is possible in it's learnings 'open' and 'short answer' questions).

This is very much asked for by teachers at technical schools. They often argue that they know it is possible in Blackboard (question types Calculated Formula Question, Numeric Answer Question) and so it should be in it's learning.
