Putting a spring into your Math journey


If your class did well on their last math test, does that mean you are a smart class, or does it mean that the test was easy? Well, that might not be easy to answer, but here is a video that will explain how forces work with springs, and that might put a spring in […]

Science needs Mathematics!


You might say, “Of course Science needs Mathematics, just as cars need engines.” In some ways, Mathematics is the glue that holds Science together. Mathematics powers the Sciences! This begs the question – “Does Mathematics need the Sciences?” “Mathematics is used in Physical Science for measurements and to show relationships. Arithmetic consists of simple operations […]

May the Force be with You!


As a growing mathematician you will need to get really good at working with formulae. That is, you need to learn how to solve simple equations and use this knowledge to work with formulae. Another way of letting you in to this gently is that it is like you need to know the road rules […]

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
