• A. 54
• B. 57
• C. 63
• D. 72

Answer: (C)

To find the product of 9 and 7, you can think of it as adding 9 together seven times: 9 + 9 + 9 + 9 + 9 + 9 + 9. Counting these up, you can group the terms for easier addition: - 9 + 9 = 18 - Another 9 gives 27 - Another 9 gives 36 - Another 9 gives 45 - Another 9 brings it to 54 - Finally, adding the last 9 results in 63. Thus, multiplying 9 by 7 indeed equals 63. Recognizing that 9 times any number can often be represented using a multiplication table or memorizing key facts can help solidify this understanding. This product is a fundamental multiplication fact that is essential to grasp for more advanced arithmetic and problem-solving skills.
