If it is the vedio in lesson 1 data handling it is that after 4 tally marks you put the the fifith tally mark across to make it into a bundle . so if you have 4 bundles and three tally marks, then you just have to multiply and then add. as 1 bundle has 5 marks you do 4x5=20, you add three because you have three more which cant be included in a bundle 20+3=23.
For silvi mary sunil. It is QUESTION instead of ANSWER.
