MATHS SYMBOLS TO NOTE FOR MATHEMATICS EXPO 2021
__________________
/ means DIVISION
* means multiplication
tita u should know dat.
rais means raise to power
^ means raise to power
sqr rut/ squar rut means square root
—(1) means equation 1
yr means year
f(xxbar) means x MINUS x BAR as in statistics
which means that MINUS WILL BE ON TOP OF x.
, (Comma) means NEXT LINE, THIS MEANS THAT THE FOLLOWING NUMBER IS UNDER THE
4 / 46
NUMBER IT IS FOLLOWING i.e UNDER.
It is
usually used during STATISTICS when drawing a
table.
X:1,2,3,4,
FX: 4,6,8,10
FXXbar: 10,8,6,4,
DRAW A TABLE WITH XFX(FXXbar)
The above statement means that:
~For X, it has 1 2 3 4 5 6 under it. which means 1
is under 2, 2 is under 1, 3 is under 2, 4 is under 3
and so on…
~Under FX you have 4, then 6 under 4, then 8g
under 6, then 10 under 8, then 12 under 10…..
~Under FXXbar you have 10, then 8 under 10,
then 6 under 8, then 4 under 6, then 2 under 4,
then 1 under 2….
IN A CLEARER WAY:
→ comma means NEXT LINE(e.g)
x : 1,2,3
fx : 4,5,6
fxxbar : 10,8,6,4
xfx fxx¯¯
1 4  10 
2 6  8 
3 8  6 
4 10 4 
Class interval:
6064,6569,7074,7579,8084,8589,9094,9599.

X: 62,67,72,77,82,87,92,97.
F: 2,3,6,11,8,7,2,1.
FX: 124,201,432,847,656,609,184,97.
F(xx bar)2:
561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.06
MEANING OF THE ABOVE EXPRESSION:
Bar means Minus on top of d number or Variable
and comma means next line which means each of
them are unda. Eg 6064 is unda Class interval,
then 6569 is unda 6064,etc .So comma means
unda.
NOTE THAT WHEN U SEE SOMETHING LIKE THE
ABOVE TWO EXAMPLES, U WILL NEED TO DRAW A
TABLE..

QUESTION 1
(1a)
Given A={2,4,6,8,…}
B={3,6,9,12,…}
C={1,2,3,6}
7 / 46
U= {1,2,3,4,5,6,7,8,9,10}
A’ = {1,3,5,7,9}
B’ = {1,2,4,5,7,8,10}
C’ = {4,5,7,8,9,10}
A’nB’nC’ = {5, 7}
(1b)
Cost of each premiere ticket = $18.50
At bulk purchase, cost of each = $80.00/50 = $16.00
Amount saved = $18.50 – $16.00
=$2.50

QUESTION 2
(2ai)
P = (rk/Q – ms)⅔
P^3/2 = rk/Q – ms
rk/Q = P^3/2 + ms
Q= rk/P^3/2 + ms
(2aii)
When P =3, m=15, s=0.2, k=4 and r=10
Q = rk/p^3/2 + ms = 10(4)/(3)^3/2 + (15)(0.2)
= 40/8.196 = 4.88(1dp)
(2b)
x + 2y/5 = x – 2y
Divide both sides by y
X/y + 2/5 = x/y – 2
Cross multiply
5(x/y) – 10 = x/y + 2
5(x/y) – x/y = 2 + 10
4x/y = 12
X/y = 3
X : y = 3 : 1

QUESTION 3
(3a)
Diagram
CBD = CDB (base angles an scales D)
BCD+CBD+CDB=180° (Sum of < in a D)
2CDB+BCD=180°
2CDB+108°=180°
2CDB=180°108°=72°
CDB=72/2=36°
BDE=90°(Angle in semi circle)
CDE=CDB+BDE
=36°+90
=126
(3b)
(Cosx)² – Sinx given
(Sinx)² + Cosx
Using Pythagoras theory thrid side of triangle
y²= 1²+√3
y²= 1+ 3=4
y=√4=2
(Cosx)² – sinx/(sinx)² + cosx
(1/2)² – √3/2/
(√3/2)² + 1/2 = 1/4 – √3/2 = 12√3/4
3/4+1/2 = 3+2/4
=12√3/4 * 4/5
=12√3/5
