## Welcome to H3 Maths

Blog Support for Growing Mathematicians

### H3 Maths Welcome Page

Welcome to H3 Maths, an area for Junior High School students to find cool Maths sites on common topics, and also to comment and ask questions on topics they are studying. The goal is to help students get organised, get interested and learn more about the wonderful, mathematical world they live in. When a student says, “I hate Maths” they are usually correct. After all, we all hate something that we are not good at!

Many students don’t like Maths because they have had no success at it. This blog aims to help students understand and do well in their Maths, or at least some mathematical topics. So, be encouraged and ask questions or add comments as you read the posts.

Hi, I am a Singaporean maths teacher. I like your h3 math blog…

Speaking of patterns in maths, I have always been interested in mathematics coming out in Nature (aesthetics) akin to some of the work Fibonacci and other renaissance mathematicians pursued.
The Mandelbrot set and fractals is also a fascinating phenomenon as well, but probably above and beyond the understanding of most school students unfortunately.

Congrats and good luck in your crusade to bring the joy and beauty of maths back to schools.

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

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)?]
