can you produce a 2-digit whole number by multiplying two-digit whole numbers?
I forgot to put the answer which is no
You're right.
Yes, you can produce a 2-digit whole number by multiplying two-digit whole numbers.
To find the product of two two-digit whole numbers, you multiply the tens digit of the first number by the tens digit of the second number and add a zero at the end. Then, you multiply the tens digit of the first number by the ones digit of the second number and write down the result as the second digit. After that, you multiply the ones digit of the first number by the tens digit of the second number and write down the result as the third digit. Finally, you multiply the ones digit of the first number by the ones digit of the second number and write down the result as the fourth digit.
To illustrate this, let's use an example: 23 multiplied by 45.
Step 1: Multiply the tens digit of the first number (2) by the tens digit of the second number (4), and add a zero at the end: 2 x 4 = 8 with a zero, so we have 80.
Step 2: Multiply the tens digit of the first number (2) by the ones digit of the second number (5): 2 x 5 = 10. Write down the result as the second digit: 10.
Step 3: Multiply the ones digit of the first number (3) by the tens digit of the second number (4): 3 x 4 = 12. Write down the result as the third digit: 12.
Step 4: Multiply the ones digit of the first number (3) by the ones digit of the second number (5): 3 x 5 = 15. Write down the result as the fourth digit: 15.
Putting it all together, we have 23 multiplied by 45 equals 1035.
So, by following this method, you can produce a 2-digit whole number by multiplying two-digit whole numbers.
