Murderous Maths

# Algebra: Functions

Simon loves functions. He hasn’t ever studid them in Algebra, but comes across functions regularly in programming.  This is what he came up with Wednesday:

I showed Simon that there is a functions course on Khan Academy:

And he watched some videos and completed some tasks:

Math on Friday:

# Math. Polynomials

From today’s math lesson. Simon has started polynomials and insisted upon expressing them as a graph:

# Inequalities Machine 2.0

Simon has nearly completed the basic equations and inequalities course on Khan Academy.

Every time his math teacher comes they solve a couple of inequalities from the course and what happens next is that Simon goes over to his desktop to check his answers in the “Inequalities machine” he programmed! He often has to change the program to fit a new inequality format, so it takes some time. Luckily the math teacher understands how awesome this is. I also think it’s the first time Simon has really programmed something for practical use!

This is how Simon solves the inequalities, by typing them:

Testing the answer in the “Inequalities Machine”:

The original “Inequalities Machine” Simon programmed back in February:

# Sums of consecutive integers

It’s been great watching Simon turn a word problem into an equation today. He was busy with “Sums of consecutive integers” (Practice finding the nth number in a sequence of consecutive numbers based on the sum) on Khan Academy.
