• Left index of C to 2 on D
• Cursor to 3 on C
• Product is 6 on D
• Right index to 6 on D at cursor
• Cursor to 4 on C

But there is a better way...

• Left index of C to 2 on D
• Cursor to 3 on C
• Product is 6 on D
• Slide to 4 on Cl at cursor

This method is a “shortcut”, which saves a step from the first method.
