What is 5 times 9?

What is 5 times 9?

• A. 35
• B. 36
• C. 45
• D. 54

Answer: (C)

To determine what 5 times 9 equals, we use the concept of multiplication as repeated addition. Multiplying 5 by 9 means we are adding 5, nine times: 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5. When you perform this addition, you can count the groups of five or add them in chunks, such as: - 5 + 5 = 10 - 10 + 5 = 15 - 15 + 5 = 20 - 20 + 5 = 25 - 25 + 5 = 30 - 30 + 5 = 35 - 35 + 5 = 40 - 40 + 5 = 45. Alternatively, another way to derive this is by grouping multiples: since 9 is the same as 10—1, we can take: (5 × 10) - (5 × 1) = 50 - 5 = 45. This method shows that multiplying 5 by 9 gives us a clear result of 45, confirming that the answer is accurate. For clarity, this also highlights the

To determine what 5 times 9 equals, we use the concept of multiplication as repeated addition. Multiplying 5 by 9 means we are adding 5, nine times:

5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5.

When you perform this addition, you can count the groups of five or add them in chunks, such as:

• 5 + 5 = 10

• 10 + 5 = 15

• 15 + 5 = 20

• 20 + 5 = 25

• 25 + 5 = 30

• 30 + 5 = 35

• 35 + 5 = 40

• 40 + 5 = 45.

Alternatively, another way to derive this is by grouping multiples: since 9 is the same as 10—1, we can take:

(5 × 10) - (5 × 1) = 50 - 5 = 45.

This method shows that multiplying 5 by 9 gives us a clear result of 45, confirming that the answer is accurate. For clarity, this also highlights the
