Q. 22200×2422200 \times 24
  1. Identify Numbers: Identify the numbers to be multiplied. We have two numbers, 2220022200 and 2424, which we need to multiply together.
  2. Set Up Multiplication: Set up the multiplication. Write down the larger number, 2220022200, and below it write the smaller number, 2424, aligning the units digits.
  3. Multiply Units and Tens Digits: Multiply the units digit of the second number 44 by each digit of the first number 2220022200, starting from the rightmost digit. Write down the result below the line.
  4. Add Products: Multiply the tens digit of the second number (22) by each digit of the first number (2220022200), starting from the rightmost digit. Remember to add a zero (as a placeholder) to the right of the result since we are now in the tens place. Write down the result below the previous product.
  5. Perform Calculations: Add the two products obtained in steps 33 and 44 to get the final result.
  6. Perform Calculations: Add the two products obtained in steps 33 and 44 to get the final result. Perform the calculations from steps 33, 44, and 55. \newlineMultiplying by the units digit of 2424:\newline\newline\begin{align*}\newline&2220022200 (\newline\)&\times\ 44 (\newline\)\hline\newline&8880088800\ \text{(This is the product of 2220022200 and 44)}\newline\end{align*}\newline\newlineMultiplying by the tens digit of 2424 (don't forget the placeholder zero):\newline\newline\begin{align*}\newline&2220022200 (\newline\)&\times\ 22 (\newline\)\hline\newline&4440044400\ \text{(This is 1010 times the product of 2220022200 and 22, hence the placeholder zero)}\newline\end{align*}\newline\newlineNow add the two products:\newline\newline\begin{align*}\newline&\phantom{+}8880088800 (\newline\)&+4440044400 (\newline\)\hline\newline&133200133200\newline\end{align*}\newline
