Solve the Basic Multiplication: 5×4 Times Tables Practice

Q: What's the difference between 5×4 and 4×5?

Great question! Both $ 5\times4 $ and $ 4\times5 $ equal 20. This is called the commutative property - you can multiply numbers in any order and get the same result!

Q: How can I remember that 5×4 equals 20?

Think of it as 5 groups of 4 or 4 groups of 5. You can also use your fingers: count by 5s four times (5, 10, 15, 20) or count by 4s five times (4, 8, 12, 16, 20).

Q: Why do I keep getting 9 instead of 20?

You might be adding instead of multiplying! Remember: 5 + 4 = 9 (addition) but 5 × 4 = 20 (multiplication). Look for the × symbol to know which operation to use.

Q: Is there a trick to learn the 5 times table?

Yes! When multiplying by 5, the answer always ends in 0 or 5. For even numbers like 4, multiply by 5 gives 20 (ends in 0). For odd numbers, it ends in 5.

Q: How can I check if 20 is the right answer?

Use division to check: $ 20 \div 4 = 5 $ or $ 20 \div 5 = 4 $. If you get back one of your original numbers, your multiplication is correct!
