Understanding the Basics

Q: How do you multiply by 15?

A: Multiplying by 15 is essentially adding a number fifteen times. For instance, 3 x 15 means adding 15 three times: 15 + 15 + 15 = 45.

Q: Is there a pattern in the fifteen times table?

A: Absolutely! Notice how the numbers in the units place alternate between 5 and 0:

• 1 x 15 = 15
• 2 x 15 = 30
• 3 x 15 = 45
• 4 x 15 = 60
• 5 x 15 = 75
• 6 x 15 = 90

Q: How can I quickly calculate 15 x 7?

A: One trick is to think of 15 x 7 as (10 x 7) + (5 x 7). This gives you 70 + 35, which equals 105.

Beyond the Basics: Tips and Tricks

Q: What are some helpful mnemonic devices?
