3. Calculation on sand
• The numbers from 1-9
are invented by Hindu
• They use a board and
sand to calculate sums
4. Calculation on hands
• In ancient time people
use their fingers to
calculate .
• No one knows that who
have invented this idea.
5. Astronomical calculation
• This method is Firstly
used by Babul
civilization.
• Then it is introduced in
astronomy so it is called
Astronomical method of
calculation
• This method is based on
60 numbers
6. Arabic Numbers
• These numbers are
used in 10th century
• Some numbers are also
used till now
7. Use of Numbers In Trade
• Due to trade People
learned the ideas of
calculation
• People share there
ideas and method of
calculation to anothers.
12. Triangles
• Triangles are also a
geometric shape
• Having three corners
• In all tri angles the
sum of all angles 180
degrees
13. Angles
• Angles are empty
space between two
surfaces .
• Angles are calculated
in degrees.
• In this diagram angle
is represented by
14. Shadow clock
• Muslim researcher
used the idea about
angles and made
shadow clock or sun
clock.
15. Right angle triangle
• Right angle is
invented by the
people of Egypt .
• They divided a rope
into 12 pieces then
they combine 5
pieces and 4 pieces
and 3 pieces of rop
16. Right angle triangle
• Then they join the corners .
• Thus the right angle triangle invented
17. Balancing equation
• This is a trick in which
we find the value of
unknown number.
• In this unknown value
is “x” and at last we
find the value of “x”
• This trick is introduced
by Al Khwarizmi
18. Al Khwarizmi
• He is a founder of a
branch of math's
name algebra
• Algebra have many
benefits
19. Shapes of math's
• these shapes are a
major part of
geometry.
• A man who have a
major part on
research in this field
is “Euclid”
20. Geometry and instruments
• Scale and compass
are use to draw
straight line and
circles.
• When we combine
these two
instruments we will
make many shapes
of geometry.
21. Ellipse
• This is a egg type
shape in geometry it
is called ellipse.
• It has simple trick to
draw
22. Conic and its part
• Cone is a basic shape
of geometry
• From cone we can
also make other
geometric shapes.
• The shapes are given
in diagram .
23. Geometry and art
• Geometry is also use
to making design
and art.
• In early days
builders use
combination
geometric shapes.
24. Geometric art
• These are some
samples of
geometric shapes
which designed on
wall to make wall
more attractive.
25. Light & optic
• Study of light and
the function of our
eyes is called optics .
• A Muslim scientist
Ibn al Haytham has
research a lot in this
field.
26. How our eyes can see
• Ibn al Haytham
explained that first
light rays strike to a
object and rays were
reflected in our eyes
thus the object will
visible to our eyes .
27. Ibn Haytham also explained that our eyes form
an image of object on retina.
28. Refraction
• When light rays
enter from denser
medium to rarer
medium it divert its
direction this
process is called
refraction .
30. Pin hole camera
•Pin hole camera is
first camera in the
world .
•It was a dark room
with a small room
where the image of
object will form on
the opposite side of
hole on wall.
31. leaser
•In now a days
leaser is a new
invention in optics
•It is use in hospitals
as a medical
apparatus
•It is also use in w ray
machines e.t.c
