Characters with this talent have a gift for calculation, with an uncanny and deeply irritating ability to work out maths in almost no time at all.
When facting such characters with mathematical problems, the gamesmaster should assume they can solve them - no matter how difficult the problem. The gamesmaster should make a test against the character's Int every turn until a successful test indicates that the problem is solved that turn. The gamesmaster can then reveal the solution.
Super numerate characters also have a +20% modifier for all Estimate tests and a +10% modifier for all Gamble tests.
