Difference between Expressions and Equations
Equations have an (=) sign and we solve it to find the value of the variable
Expressions do not have an (=) sign and only have operations

Difference between Area and Perimeter
Area is the inside part of a figure and the amount of space taken up by the figure
Perimeter is the boundary of the figure

Formula of Area and Perimeter of a Square, Rectangle and Triangle
Square - Area = Side * Side
Perimeter = S + S + S + S
Rectangle - Area = L * B
Perimeter = L + B + L + B
Triangle - Area = 1/2 * b * h
Perimeter = Sum of all sides

Formula for Area and Perimeter of Parallelogram, Trapezium and Circle
Formula for Volume
Parallelogram - Area = b * h
Perimeter = Sum of all sides
Trapezium - Area = 1/2 * h * sum of parallel sides
Perimeter = Sum of all sides
Circle - Area = pi r 2
Perimeter = 2 pi r
Volume - Area of cross section * depth

Volksota - 12%
Toywagen - 8%
Nindai - 7%
Hyussan - 11%
Find the probability that the next car to use on road is not a Toywagen or a Nindai
P (not a Toywagen or Nindai) + P (a Toywagen or Nindai) = 100%
P (not a Toywagen or Nindai) + 8% + 7% = 100%
P (not a Toywagen or Nindai) + 15% = 100%
-15% -15%
P ( not a Toywagen or Nindai) = 85%
= 0.85

Convert m 2 to cm 2
63.5 m 2 = ______ cm 2
63.5 * 1 m *1 m
= 63.5 * 100 cm * 100 cm
= 63.5 * 10000 cm 2
= 635000 cm 2
