Re-calculating an Expression

You can edit a calculation expression in the calculation history and then re-calculate the
resulting expression. Tapping w re-calculates the expression where the cursor is currently
located, and also re-calculates all of the expressions below the current cursor location.

Example 1: To change the expression “ans

× 2” to “ans × 3” in the example below, and then

re-calculate

u ClassPad Operation

(1) Tap to the right of the expression “ans

× 2” to locate the cursor there.

(2) Delete “2” and input “3”.

Kd

(3) Tap w.

• This re-calculates the expression where the cursor is located, and all the expressions

underneath it.

Important!

Remember that re-calculation is performed starting from the current cursor location. If, after
performing the first two steps of the above procedure, you move the cursor to the end of
“ans + 6” in line 3 of the calculation history and then tap w, only line 3 is re-calculated.

located in the uppermost line that you edited before you tap w.
