Which number is the odd one out?

January27

These talented young dancers are doing a routine for a judge – who will score them using their numbers. Above them are two more numbers, making the sequence 5, 7, 2, 5 or (top to bottom) 7, 5, 5, 2. My students enjoyed coming into class and, when seeing four numbers on the board, trying […]

It was one of those nasty family surprises – a family member having an emergency visit to hospital. As the nurse was making the patient comfortable, she was also busy checking the vital stats and noting them down in her log. Her comment was, “It’s all about numbers and I can’t do my job without […]

An Odd bit of Math

December10

ODD and EVEN NUMBERS. The Pythagoreans knew of the distinction between odd and even numbers. The Pythagoreans used the term gnomon for the odd number. A fragment of Philolaus (c. 425 B. C.) says that “numbers are of two special kinds, odd and even, with a third, even-odd, arising from a mixture of the two.” […]

Words began with numbers!

“Much like today’s tablets, writing at length on the world’s first tablets was a pain in the neck. Fire-hardened clay tablets were really only convenient for scribbles and straight lines, just enough for simple accounting with graphic symbols and tick marks. “Words, in a sense, began with numbers” says Peter Watson in his superb book […]

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Popular Math Problems Answers: 1, 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Number of different nets to make a cube is eleven – see this link

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

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)?]
