A math line lets you input a calculation into an eActivity fi le, and then perform the same

Math lines always have two parts: an input expression and a result.
eActivity calculations are different from RUN
• When you input a mathematical expression into an eActivity, the Input Mode (page
1-3-10) always changes to "Math", regardless of the calculator's current input mode
setting.
Note that the word wrap function does not apply in the case of math lines. Arrow
