A specific learning difficulty in mathematics and/or dealing with numbers. In most cases this can be tackled by taking a different approach to the traditional ones used in this area. What is the underlying cause of this problem Steve Chin , a specialist in this area, has pinpointed 'poor short term and working memories , both of which are key pre-requisite skills for mental arithmetic and indeed mathematics in general'. Because traditional maths teaching relies heavily on memorising facts and processes this can create a significant barrier to learning from the outset In Chin's view this problem is exacerbated by a focus on memorising facts (e.g learning tables) rather than understanding Mathematical processes: Better performing peers use linking strategies which are based on understanding numbers, operations and how they relate.

This is because the cost of insuring government debt is calculated to basis points as this recent example from the financial press shows:  Italian five-year CDS was 69 basis points wider at 512 basis points, nearing its record of 521 basis points hit on Sept. 21, according to data-provider Markit.
