You can position the cursor anywhere on the calculation line using the pen or
the arrow keys.
Operator precedence
Operator precedence in the Scientific view is as follows (highest first):
• Information in brackets.
• Functions which follow the value to which they refer, e.g. x!
• Powers.
• ,mplicit multiplication before a memory value, i.e. 30A.
• Prefix functions which precede the value they refer to, e.g. sin.
• Implicit multiplication before prefix function, such as 5sin30,
or before an open bracket, as in 4(4+5).
• Multiplication and division equal, calculated left to right.
• Addition and subtraction equal, calculated left to right (lowest).
See the MC 218 help for more about entering expressions and operator
precedence in the Scientific calculator.
Re-using answers and calculations
In the Scientific view you can re-use the answer from your last calculation.
To insert the last answer at any point in a calculation:
• Tap the Ans button at the appropriate point. The calculator will insert
‘Ans’ in the calculation line, representing the last result.
To start a new expression with the last answer:
• Just enter the rest of the expression as though the answer was already
written at the start. The calculator will prefix the expression with
‘Ans’.
You can also re-use and edit calculations you have performed earlier. This can
save time if you want to perform a new calculation which differs only slightly
from a previous one.
To re-use a previous expression:
• Use the up and down keys, or Edit previous and Edit next on the Edit
menu, to display the last 10 calculations one by one on the calculation
line. When you find the expression you want to re-use, change it if
required and proceed as normal.
Note! The value of Ans used in a calculation will always be the value of the
last calculation. If you re-use a calculation based on a value of Ans, the result
will be calculated using the current value of Ans rather than the value at the
time of the original calculation.
