Learning comes first through exercise, attempts and failures. When training, it is normal to make mistakes and have to start all over again. These mistakes are part of the learning process and help us move forward.
FriXion Ball pens help keep your worksheet clear and clean. At the slightest mistake, you just have to modify your calculations, erase and start again.

 In addition, thanks to the many colours of the pens, it is much easier to differentiate the elements and to better segment the variables of your equation. Therefore, you have the best tools in hand to take your time and start again until you can solve your equation.
Your maths exercises are clearer and you make progress faster!
