Multiply decimals by 10, 100 and 1,000.
Perform multiplication to solve mathematical equations.

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Shift digits to the left: When multiplying by 10, 100, or 1,000, every digit moves to the left to make the number larger.

– × 10: Move digits 1 place to the left (e.g. 0.45 × 10 = 4.5).

– × 100: Move digits 2 places to the left (e.g. 0.45 × 100 = 45).

– × 1,000: Move digits 3 places to the left (e.g. 0.45 × 1,000 = 450).

• Count the zeros: The number of zeros in 10 (1 zero), 100 (2 zeros), or 1,000 (3 zeros) tells you how many place value columns to shift digits to the left.

💡 Tips

• Use zero as a placeholder: If you run out of digits when shifting to the left, fill the empty ones column or place value spaces with zero. For example, 3.2 × 100 = 320.

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Just type plain digits or decimals like 4.5, 45, or 450 without adding any spaces, commas, or extra words.

⚠️ Warnings

• Do not just “add zeros” to the end of a decimal: Adding a zero to the right of a decimal point does not change its value (e.g. 0.450 is still equal to 0.45)! You must shift the digits across the decimal point.

• Do not move digits to the right: Moving digits to the right makes a number smaller (division). Remember that multiplication always makes numbers larger!
