To find the product of 24 and 32, we need to multiply these two numbers together. Let's break down the process step by step:
Step 1: Write down the numbers
- Write down the number 24.
- Write down the number 32.
Step 2: Multiply the ones place
- Multiply the digit in the ones place of the first number (4) with the digit in the ones place of the second number (2). The product is 8.
Step 3: Multiply the tens place
- Multiply the digit in the tens place of the first number (2) with the digit in the ones place of the second number (2). The product is 4.
Step 4: Multiply the hundreds place
- Since the first number does not have a digit in the hundreds place, we can skip this step.
Step 5: Multiply the thousands place
- Since neither of the numbers has a digit in the thousands place, we can skip this step.
Step 6: Write down the partial products
- Write down the products from Step 2 (8) and Step 3 (4) next to each other.
Step 7: Add the partial products
- Add the partial products together. 8 + 4 = 12.
Step 8: Write down the final product
- Write down the final product, which is 12, next to the partial products.
Therefore, the product of 24 and 32 is 768.
In this case, the correct answer is option 'C' (768).
Step 1: Write down the numbers
- Write down the number 24.
- Write down the number 32.
Step 2: Multiply the ones place
- Multiply the digit in the ones place of the first number (4) with the digit in the ones place of the second number (2). The product is 8.
Step 3: Multiply the tens place
- Multiply the digit in the tens place of the first number (2) with the digit in the ones place of the second number (2). The product is 4.
Step 4: Multiply the hundreds place
- Since the first number does not have a digit in the hundreds place, we can skip this step.
Step 5: Multiply the thousands place
- Since neither of the numbers has a digit in the thousands place, we can skip this step.
Step 6: Write down the partial products
- Write down the products from Step 2 (8) and Step 3 (4) next to each other.
Step 7: Add the partial products
- Add the partial products together. 8 + 4 = 12.
Step 8: Write down the final product
- Write down the final product, which is 12, next to the partial products.
Therefore, the product of 24 and 32 is 768.
In this case, the correct answer is option 'C' (768).

The product can be found by simple multiplication: 93 * 27 = 2511
Here is a quick trick:
Step 1: You can simplify the calculation by splitting 93 into 90 and 3.
Step 2: Multiply 27 by both of these numbers separately. 27 * 90 = 2430 27 * 3 = 81 Step 3: Add these two results together. 2430 + 81 = 2511 So, 93 * 27 = 2511.
