On thursday I will be down near your area, giving another family some extra help at 19:00
From 17:00 to 19:00 I am free, do you need some help on maths or science lessons.
If you do need help, just let your dad know that I am coming (as a permission from him).
'Front elevation' Is this has to do with triangle?
I am not sure i did not have a triangles picture in it .It might be i dont understand this question can you help?
A football club's players do as many press-ups as they can in one minute. This stem-and-leaf diagram shows the results.
2 l 7 8
3 i 1 2 3 5 7 8 9 9
4 n 0 1 2 4 5 6 9
5 e 0 1 3 6
(a) How many players are in the football club?
(b) What was the range of press-up scores?
(c) The coach says that the median and modal numbers of press-ups were the same. is he correct ? show your working out. — do you know the question when they give you a graph and there is a trapezium in the graph and they ask you to find the centre of enlargement
[edit] Please read this
These kind of questions are hard to answer here sisters, it requires in the class first then I can write them here
But in the main time I will revise and go throught all other topics you haven't cover yet
I will list all the topics here
If you both wish I could go through any topic that you want to study
Please READ all these works and try and do the exercises I put here
[edit] Operations in Arithmetic
Signs of number + or -
A number without a sign in front is consider to be + number
Multiplication of positive and negative numbers
( + 1)( + 1) = + 1
( − 1)( − 1) = + 1
Note: same in signs in multiplication results in positive answer
( + 1)( − 1) = − 1
( − 1)( + 1) = − 1
Note: difference in signs in multiplication results in negative answer
Pattern of multiplication of signs
( + 1)( + 1) = + 1
( + 1)( + 1)( + 1)( + 1) = + 1
( + 1)( + 1)( + 1)( + 1)( + 1)( + 1) = + 1
Do you see the pattern?
( − 1) = − 1
( − 1)( − 1)( − 1) = − 1
( − 1)( − 1)( − 1)( − 1)( − 1) = − 1
Do you see the pattern?
Basic of addition and subtraction rules
First rule
3 + ( + 3) = 3 + 3 = 6
3 + ( − 3) = 3 − 3 = 0
Second rule
3 − ( + 3) = 3 − 3 = 0
3 − ( − 3) = 3 + 3 = 6
Addition of "positive numbers"
( + 1) + ( + 1) = + 1 + 1 = + 2
( + 1) + ( + 2) = + 1 + 2 = + 3
( + 1) + ( + 3) + ( + 4) = + 1 + 3 + 4 = + 8
Do you see the pattern
Addition of "negative numbers"
( − 1) + ( − 1) = − 1 − 1 = − 2
( − 1) + ( − 2) = − 1 − 2 = − 3
( − 1) + ( − 3) + ( − 4) = − 1 − 3 − 4 = − 8
Do you see the pattern
Subtraction of "positive numbers
( + 1) − ( + 1) = + 1 − 1 = 0
( + 2) − ( + 1) = + 2 − 1 = + 1
Do you see the pattern
Subtraction of "negative numbers
( − 1) − ( − 1) = − 1 + 1 = 0
( − 2) − ( − 1) = − 2 + 1 = − 1
Do you see the pattern
[edit] Factors and multiples
[edit] Fractions
Fraction means broken. 1/2 1/4 are broken parts of a whole
Example of fractions:
Type of fractions
There are three types:
This is called proper fraction "When the top number is smaller than the bottom number"
This is called an improper fraction "When the top number is bigger than the bottom number"
This is called an mixed fraction "whole number mixed with proper fraction"
The top number is called the numberator and the bottom number is called the denumerator
Addition of fractions
Baic rule of addition and subtraction of fractions
Rule 1: Never add the denumerator
Rule 2: Make sure the denumerator are the same
Example 1: Addition
Case 1: Where the denumerator are the same
Example 2: Addition
Case 2: Where the denumerator are not the same
Addition of algebraic fractions
Example 1 & 2:
Case 1: Where the denumrator are the same
Example 1:
Case 1: Where the denumrator are not the same
Multiplication fo fraction
When you multiply fraction just multiply the numerators and denumerators directly as shown below

[edit] Ratio and proportion
ratio is basicly used to share money or inherits.
DID YOU KNOW THAT RATIO IS ONLY BUT ANOTHER KIND OF FRACTION.
[edit] THE STAGES OF HOW TO SOLVE RATIO PROBLEMS
If you are given the question share £330 in the ratio of 3:2.
1. First you add the ratio 3+2=which is 5
2. Then you divide the money given to you by the number 5 which came from stage 1. 330divisionsign5=66
3. then you times it by the number in you ratio both of them. there you go you have your money. '66x3=198. 66x2=132. so the answer for my question''''
198:132
