Test 2. Time:50 minutes 06/08/20

Good morning students, I hope those of you who attempted the first test were able to get above half of the questions right. If you didn’t, don’t be discouraged. Simply go through the solutions of the questions you go wrong and learn from your mistake. Remember, failure isn’t failure if you learn from it.

Below I will upload another set of questions for you to attempt in your spare time (50 minutes). I will upload the solutions on Saturday night. So you can mark your work and have an idea of the kind of score you could have when you write mathematics in your state exams ( Next Tuesday 11/08/20)

FACTORIZATION 09/06/20 TUESDAY

Good morning students. i hope you have all found the past revisions helpful. i also hope you attempted the exercises that follow each module YOURSELF. if you did, you have just earned 5 stars in respect from your teacher.

Today, we would be revisiting the topic factorization. please take your time to go through the notes and examples. i will also try to accompany it with a voice note to make it easier to understand (if i can figure it out). for those of us who are finding it hard to read the download, i will include some screen shots from my phone although, it will be advisable to download a word document reader or PDF reader. i will include everything so that everybody will be accounted for. If you found this material helpful, please send us a feedback through the feedback form below the screen shot note. I will also appreciate any constructive criticism that would help us to serve you better. Thank you.

Good morning students. here is a quick summary on what you ought to remember in VARIATION with examples. There are also questions to attempt this week.

sincerely hope you were able to make some sense of the previous work above. Today, we will be looking at the topic “WORD PROBLEMS” this aspect requires interpretation of simple English words into algebraic expressions or equations. if mastered properly, it can really raise the bar of your mathematical understanding. hope you enjoy it.

Good morning students! Hope you’re staying safe. Here are some questions for you on SIMULTANEOUS EQUATIONS:

Use both Elimination (first five) & Substitution(other five) methods

hello everyone, its good to be back through this medium. our revision of topics covered in the first and second term would commence immediately. below are the topics that have been covered so far.

FIRST TERM

Binary System

Word problems

Factorisation 1: Common Factors

Area Of Plane Shapes

Formulae: Substitution and Change Of Subject Of Formula

Similarity 1: Similar shapes and Scale Factor

Trigonometry 1: tangent of angle.

SECOND TERM

Factorisation 2: Quadratic Expressions

Equations 1: Equations with Fractions.

Compound Interest

Similarity 2: Area and Volume of Similar Shapes.

Equation 2: Simultaneous linear Equations

Trigonometry 2: Sine and Cosine of Angles

statistics

Rational and Irrational numbers

BINARY SYSTEM

DEFINITIONS

Denary: This is base ten number system. most people count in tens, using the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.

Binary: this is base two number system. it uses only 1 and 0.

other number base systems exists also like base 5, base 3, base 7, base 8 and use digits less by 1 in their number system.

Converting base ten to other bases

to convert a number from base ten to another base, use repeated division as follows:

divide the base ten number by the new number base.

continue dividing until 0 is reached, writing down the remainder each time

start at the last remainder and read upwards to get the new base.
