Practice Multiplying by Powers of 10

① This interactive exercise demonstrates how to multiply numbers by powers of 10 (e.g., 10, 100, 1000), allowing users to input answers and receive immediate feedback on decimal point shifts and place value. ② Core math concepts include place value, decimal multiplication, exponent rules, and the movement of the decimal point. ③ Construction highlights: uses GeoGebra objects such as Textfield, InputBox1, and TryAnother button to build the practice interface; variables (ans, decnum, mult, usernum) store the problem and user response; conditional checks (RightCheck, WrongCheck) and feedback texts (Feedback, FbCorrect, FbWrong1, etc.) provide correctness feedback; random generation via NumPlaces and multindex varies difficulty. ④ Suitable for upper elementary to middle school students, for classroom practice or self-study of multiplication and decimal place value.
