Multiply decimals by integers.
Perform multiplication to solve mathematical equations accurately.

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Multiply as whole numbers first: Ignore the decimal point and multiply the numbers as if they were both integers (e.g. for 3.24 × 6, first calculate 324 × 6 = 1944).

• Count and place the decimal point: Count the total number of decimal places in the original question and insert the decimal point so your answer has the exact same number of decimal places (e.g. 3.24 has 2 decimal places, so 1944 becomes 19.44).

💡 Tips

• Use estimation to check your answer: Round the decimal to the nearest whole number to estimate the answer first (e.g. 3.24 × 6 is roughly 3 × 6 = 18, which confirms 19.44 is reasonable, not 194.4 or 1.944).

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Just type plain digits or decimals like 19.44 or 7.5 without adding any spaces, words, or extra symbols.

⚠️ Warnings

• Align decimal points in column multiplication: If using short or long multiplication, keep the decimal point aligned directly above in your answer line, or insert it after counting places.

• Do not drop placeholder zeros too early: If your multiplication ends in a zero (e.g. 0.25 × 4 = 1.00), keep the zeros while counting decimal places before simplifying to 1.
