Everything always changes from time to time. Now in math class, we have continued to the new book is called “5B”. The first start of the book is about decimal and we just review again about (Addition, Subtract, Multiplication, and Division). Moreover, this is the same lesson that we have learned before, but it is also still an interesting and necessary lesson. There are also rules for multiplication and division:
Multiplication:
*10 move decimal one place to the right
* 1oo move decimal two places to the right
Division:
/10 move decimal one place to the left
/ 100 move decimal two places to the left
