BOB the Snail

We have finished the unit on Counting. In this unit, I found it very interesting because it exercises the logical thinking of the students. In this unit, we learned how to use the "Pick" Formula and the "Choose" formula. These two formulas are NOT similar. These 2 terms may be synonyms, but they work differently. The "Pick" formula is used when the order of the objects matter without repetition. The "Choose" formula is used when the order of the objects doesn't matter. We should remember that these two formulas are DIFFERENT.

I hope everyone will study hard for the dreadful test. =D
