3. Words to inspire you
-GALILEO GALILEI
Mathematics is the
language in which
God has written the
universe.

4. Properties of Integers
Closure property - a + b = a unique integer
01
Commutative property - a + b = b + a
02
Associative property - (a + b) + c = a + (b + c)
03
Distributive property - a x (b + c) = a x b + a x c
04

5. Properties of Integers
Multiplicative property - a x 1 = a
05
Additive property - a + 0 = a
06
Additive inverse - a + (-a) = 0
07
Multiplicative inverse - a x 1/a =1

Types of Fraction
PROPER
FRACTION
When numerator is smaller
then the denominator, the
fraction is called as
proper fraction
IMPROPER
FRACTION
When numerator is
greater then the
numerator, the fraction is
called as improper
fraction
MIXED
FRACTION
Combination of whole
number and fraction, the
fraction is called mixed
fraction

Theorem

25. To go from a fraction to a percentage,
we can convert to a decimal first.
Percentage Fraction Decimal
30% 30/100 0.3
3/5 0.6 60%
Comparing Quantities

26. Important
Formulae
Profit = Selling Price - Cost Price
01
Loss = Cost Price - Selling Price
02
Profit % = (Profit x 100)/Cost Price
03
Loss % = (Loss x 100)/Cost Price
04

27. Selling Price = Cost Price + Profit
05
Selling Price = Cost Price - Loss
06
Cost Price = Selling Price + Loss
08
Cost Price = Selling Price - Profit
07

28. SI = (P x R x T) / 100
09
P = (SI x 100) / (R x T)
10
R = (SI x 100) / (P x T)
11
T = (SI x 100) / (P x R)
12
Amount = P + SI
13
SI = Simple Interest
P = Principal
R = Rate
T = Time
