Blog Support for Growing Mathematicians

### Thanks a million….oops, 10,000!

October25

Thanks for supporting H3Maths. We have now reached 10,000 hits on the blog which we never thought would happen, ever! Many students have enjoyed the way that we connect Mathematics with the real world, simplify important classroom concepts, and focus on career opportunities that require (or don’t require) a basic mathematical interest. So, from the bottom of our hearts – THANK YOU!! Drop us a quick email or short message to say what you have enjoyed or would like to see in future posts and we will do our best to meet the needs of our growing mathematicians out there!

PS: Many languages have a specific word for this number: in Ancient Greek it is μύριοι (related to the word myriad in English), in Aramaic ܪܒܘܬܐ, in Hebrew רבבה (revava), in Chinese 萬/万 (Mandarin wàn, Cantonese maan6, Hokkien bān), in Japanese 万/萬 [man], in Korean 만/萬 [man], and in Thai หมื่น [meun]. It is often used to mean an indefinite very large number.

• In scientific notation, it is written as 104.
• It is also written as 1 E+4 (or as 1 E4)
• It is the square of 100
• It is the square root of 100,000,000
• A myriagon is a polygon with 10,000 sides.
• 10 km, 10,000 m, or 1 E+4 m is equal to:
• 6.2 miles
• side of square with area 100 km2
• radius of circle with area 314.159 km2
• The classical Greeks used letters of the Greek alphabet to represent Greek numerals: they used a capital letter mu (Μ) to represent 10000, whose name in Greek is myriad.

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)?]
