Solve the Number Sequence: 2 × 5 × 3 Step-by-Step

Q: Does the order I multiply matter?

No! Multiplication is commutative, so you can multiply in any order. You could do $ 5 \times 3 = 15 $ first, then $ 2 \times 15 = 30 $. The answer is always the same!

Q: Can I multiply all three numbers at once?

It's better to work step by step with two numbers at a time. This reduces errors and makes checking easier. Once you're more experienced, you might recognize some patterns!

Q: What if I get a different answer?

Double-check each step! Make sure you're multiplying (not adding) and that you calculated $ 2 \times 5 = 10 $ correctly before moving to the next step.

Q: How can I check if 30 is correct?

Try working backwards: $ 30 ÷ 3 = 10 $, and $ 10 ÷ 5 = 2 $. If you get back to your starting numbers, your answer is right!

Q: Why do we multiply from left to right?

It's the standard convention that makes calculations easier to follow and check. While the final answer is the same regardless of order, working left to right keeps your steps organized.

Understand the problem

$2 \times 5 \times 3 =$

Step-by-step solution

First, we calculate the product of the first two numbers: $2 \times 5 = 10$ .

Then, we multiply the result by the third number: $10 \times 3 = 30$ .

Therefore, $2 \times 5 \times 3 = 30$ .

Final Answer

Key Points to Remember

Essential concepts to master this topic

Order Rule: Multiply from left to right one step at a time
Technique: First calculate $2 \times 5 = 10$ , then $10 \times 3 = 30$
Check: Count factors (three numbers) and verify final product is reasonable ✓

Common Mistakes

Avoid these frequent errors

Adding numbers instead of multiplying
Don't calculate 2 + 5 + 3 = 10 instead of multiplying! This completely changes the operation and gives a much smaller result. Always remember that × means multiply, not add - work step by step: 2 × 5 = 10, then 10 × 3 = 30.
