Meeting Maths Challenge. We have spent over ten years teaching mathematics in primary school, JSS,SSS and during this time I have never found any quick fixes or instant recipes for passing Mathematics in BECE and WASSCE. It is a subject which can be very demanding and tests ones ability to persevere.Meet these demands and the subject can become very rewarding. How do you meet the challenge? Arithmetic and Algebra are the key branches of mathematics.You have to be a master in both before you can do well in the other branches. These Branches of Mathematics are listed below. • Arithmetic • Algebra • Geometry • Trigonometry • Statistics • Calculus Do not rely on reading alone or depend on all what you are getting from your school maths teacher.You must do questions. Even when you think you know how to do a topic, along comes a question which can be phrased in a way that you have never seen before and this may throw you. The more practice you have from different sources the more c

Maths Preparation for 2018 Waec #Equation/#Identity- what’s the difference? Many students often used equation and identity,but they don’t know the difference between them and what notation do we use. Well, this post will aim to explain the difference. An equation contains ( = ) An identity contains ( ≡ ) Where, ( = ) means “equal to” ( ≡ ) means “can be written as” #IDENTITY Supposed you were asked to find x below. 2(x+3) = 5x-3(x-2) Expanding the brackets gives: 2x+6 = 5x-3x+6 Combine like terms on the RHS : 2x+6 = 2x+6 Subtract 2x from both sides : 6 = 6 This may sounds confusing, getting the same number value on each side when you are asked to find x. This shows that the LHS is exactly the same as the RHS. They are identical. Therefore,the expression above should be written as : 2(x+3) ≡ 5x-3(x-2) It’s an identity! An identity is true for any value.For example,let’s plug in 2 into the identity. That’s ,when x = 2 : 2(2+3)≡5(2)-3(2-2) ∴ 10 ≡ 10 Let’s also try
