Things to keep in mind when using your graphing
calculator to solve number problems:
1.
Do not confuse the subtraction key with the
negation key.
When you look at the subtraction symbol on the screen, it will appear
to be slightly wider and lower set than the negation symbol.
2.
There are two ways to square a value.
The carrot symbol can be used to
raise a value to any power.
Squaring can be accomplished by using the "squared" key or
by raising the value to the power of 2 with the use of the
^ (carrot) symbol.
3.
Remember the need for parentheses.
Be careful with parentheses. Some functions, such
as square root, automatically start a left parenthesis for
you. YOU must be sure to tell the calculator when to
close the parenthesis.
Parentheses are also important when evaluating
expressions. Remember that in the order of
operations, if there are no parentheses present, powers
will be done BEFORE the assigning of negative status.
4.
There
are several ways to deal with the radical symbol.
The square root symbol is above the "squared" key.
The cube root and higher roots are found under the MATH
key.
When finding a higher root, enter the
root number first, then use MATH #5, then type the value.
