October 4, — Peter Barendse Comments Off What do the following two math problems have in common? If I have 12 apples, and Jane has 7, and then Jane gives 2 apples to me, how many more apples do I have than Jane?
First, the two problems are essentially the same; the latter is just expressed in the language of symbolic mathematics. Second, Wolfram Alpha can now solve both!
Did you find the second problem easier? After all, this is why mathematical symbols were invented: Once expressed in symbols, solving a math problem is relatively easy. Software programs like Mathematica know almost all these algorithms and can solve pretty much any symbolic problem you can think of.
But knowing how to solve symbolic math problems is like knowing how to use a saw to cut wood and a hammer to drive nails. This is where Wolfram Alpha can help. Word problems are an important part of our mathematical education because real-life problems almost never present themselves to us in symbolic form.
They are usually given in the form of a story, which we translate into symbolic math in order to solve. This is what Wolfram Alpha does with elementary word problems: You can ask Wolfram Alpha to solve any problem where people or letters have some common objects like apples and then gain, lose, or swap these objects.
Wolfram Alpha knows to ignore any irrelevant information and shows a calculation and illustration to help you understand how the numbers in the problem were used to find the solution.Wooden Jack Puzzle.
