Online quiz: Subtracting decimals with varying decimal places

📚 Quick Study Guide

• 🔢 When subtracting decimals, always align the decimal points. This ensures you're subtracting tenths from tenths, hundredths from hundredths, and so on.
• ✏️ If one number has fewer decimal places than the other, add zeros to the end of the shorter number so that both numbers have the same number of decimal places. These added zeros don't change the value of the number.
• ➖ Subtract the numbers as you would with whole numbers, starting from the rightmost column.
• 📍 Bring the decimal point straight down into your answer, aligning it with the decimal points in the numbers you subtracted.
• 💡 If the top number in a column is smaller than the bottom number, you'll need to borrow from the column to the left, just like in regular subtraction.
