So, they must have the same numbers in each corresponding position. Example 2: If A=(812n)A=(812n) , B=(4m−3)B=(4m−3) and A=BA=B, find the value of mm and nn. Solution: It is given that AA is a row matrix and B=(4m−3)B=(4m−3) and matrix AA equals ...
Participants were instructed to name the colour (for the first and third parts) or words (for the second part) as quickly as they could. The first five items in each part served as practice for task familiarization. Participants' performance was indicated by the inverse difference in the time...
In this article, we worked on different word problems using the concept of fractions of the remainder. We can solve such problems by different methods. We can draw models, use the branching method or the unitary method. As always, practice, practice, and more practice will give you the ...
Different light sources produce light with slightly different colour tints, but our eyes do a great job correcting these variations. Humans do not see a shift in colour as we move from a sunny garden into a shaded area, or go into a room and turn a light on. Generally wherever we are,...
(This is surely the right thing to say about imagining a new colour, as discussed earlier.) So if space has in fact always appeared as Euclidean in our perceptions so far, that could explain why we cannot picture it otherwise. But the case of logic is different, and if here again ...
Next step was the colouredPic-a-Pix. I had not had the possibility to teach them so far because we simply don’t have a colour printer to use in day-to-day teaching. Now, however, with the new Flash puzzle games on the site the puzzles were a great success. Some of the students ...
“Eddie Woo’s gift is in using stories to help us see the way maths breathes life, colour, shape, and rhythm into the world around us. He’s transformed the lives of countless students in his classroom and on Wootube. Now he’s here to change how you see numbers too – whether you...
(issue 4, page 99). A third example (grade 6, issue 3, page 114) presents four children, two have masculine names (Angelos, Christos) and two have feminine names (Anna, Elli). Pupils need to use the given information to find the colour of each child’s notebook. In the information...
“A ratio is a sort of relation in respect of size between two magnitudes of the same kind”:Euclid, book V definition 3). A (particular) ratio is thus not merely a “place in a structure” (of all ratios), for the same reason as a colour is not merely a position in the space ...
In this article, we will learn about two topics of coordinate geometry in the Mathematics subject; the Equation of a Straight Line & Geometrical Problems Involving Coordinates. This article is meant for Secondary 3 students. Topic Overview: Interpret and find the equation of a straight-line graph...
