The best way to study for any test is to practice.
Notes for Equations :
Solving
an equation means finding a value of a variable that make the equation true.
This value is called the solution of the equation. A mathematical equation is
just like a balanced equation. Both sides of the equation should be equal at
all times. Whatever we do to one side, has to be done on the opposite side.
Solving
equations with variable on both sides, you have to move all terms to one side
and rest constant terms to other.
Notes for Powers
A Power
is a short way to represent repeated multiplication. The power includes a base
and an exponent. The base is the number that is multiplied. The exponent is the
number of times the base is multiplied.
Note: The
power of a negative base is positive if the exponent is even, and negative if
the exponent is odd.
