#### Simple Mathematical Modelling

At both the junior and senior secondary school levels in Nigeria, student performance in mathematics examinations has been poor. Within the context of large classes, with inadequate facilities, and teaching and learning in a second language, algebra and algebra word problems are introduced to students during their first year of junior secondary school. The transition from primary school arithmetic to the use of the algebraic letter is challenging to students and it is important that teachers should know the likely difficulties and misconceptions students may have as they begin algebra…

#### Binary Operation Worksheet and Solution

(0)
Below you could see some problems based on binary operations. Solved Examples Question 1: The binary operation * defined on Z by x * y = 1-2xy. Show that * is cumulative and associative. Solution: Given x * y = 1-2xy Binary operation is cumulative, since x * y = 1-2xy = 1-2yx = y * x =&gt; x * y = y * x * is cumulative. Now, check * is associative x * (y * z) = x * (1-2yz) = 1-2x(1-2yz) = 1-2x + 4xyz and (x * y) * z = (1-2xy) * z = 1-2(1-2xy)z = 1-2z + 4xyz =&gt; x * (y * z) ≠≠ (x * y) * z Thus, we can find that * is not associative on Z. Question 2: The binary operation * defined on Z by x * y = 1 + x + y. Show that * is cumulative and associative. Solution: Given x * y = 1 + x + y Binary operation is cumulative, since x * y = 1 + x + y = 1 + y + x = y * x =&gt; x * y = y * x Therefore, * is cumulative. Now, check * is associative x * (y * z) = x * (1 + y + z) = 1 + x + 1 + y + z = 2 + x + y + z (x * y) * z = (1 + x + y) * z = 1 + 1 + x + y + z = 2 + x + y + z x * (y * z) = (x * y) * z Thus, * is also satisfies associative property. A binary operation on a set is a calculation involving two elements of the set to produce another

#### Complete Work on Calculus

The concept of a limit is fundamental to Calculus. In fact, Calculus without limits is like Romeo without Juliet. It is at the heart of so many Calculus concepts like the derivative, the integral, etc. So what is a limit? Maybe the best example to illustrate limits is through average and instantaneous speeds: Let us assume you are traveling from point A to point B while passing through point C. Then we know how to compute the average speed from A to B: it is simply the ratio between the distance from A to B and the time it takes to travel from A to B. Though we know how to compute the average speed this has no real physical meaning.
