- Enter your equations one by one in
CAS, pressingEnterto start a new row for each of your equations. - 3.
- Select each of the rows with an equation in them by clicking the boxes with a row number. You’ll know that the row is selected when the box with the row number has turned purple. To select more than one box at a time, hold down the
Shiftkey, click the box of the first equation and then click the box with the row number of the last equation. - 4.
