How to multiply a two digit decimal from a three digit decimal

The video tutorial covers subtraction and multiplication rules, focusing on aligning numbers and decimal points. It explains the importance of subtracting larger numbers from smaller ones and provides a detailed walkthrough of multiplying decimals, including aligning decimal points and determining the final decimal placement in the result.

What is the golden rule for subtraction?

• Subtract numbers randomly.

• Subtract only if the result is positive.

• Always subtract the smaller number from the larger one.

• Subtract the larger number from the smaller one.

When multiplying decimals, how should the numbers be aligned?

• Align the larger number below the smaller one.

• Align the numbers randomly.

• Align the smaller number below the larger one.

• Align the numbers horizontally.

What is the first step in the multiplication algorithm after aligning the numbers?

• Ignore the decimal points completely.

• Add the numbers directly.

• Multiply the numbers without considering place values.

• Multiply each digit starting from the rightmost side.

How do you determine the final position of the decimal point in the result?

• Place the decimal point at the end of the number.

• Ignore the decimal point entirely.

• Count the total number of decimal places in both numbers.

• Place the decimal point at the start of the number.

What should you do with the numbers carried over during multiplication?

• Ignore them.

• Multiply them separately.

• Subtract them from the result.

• Add them to the next multiplication step.
