I had a problem this week, with multiplying two matrices. They were a 2x3 and a 3x2 matrix, and I sometimes get muddled in which numbers need to be added to which others.
Mathcad to the rescue! I punched in the numbers, and out popped the result. I did the maths using pencil, paper and grey matter, and then used Mathcad to verify.
In situations like this, it has started to become a bit of a life saver as it stops all of those silly errors in counting.
In a future post, I will give an evaluation of the Mathcad functions, both good and not so good. It is starting to become a useful tool, as it is helping in the checking process, as part of an overall maths problem solving strategy.
