Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the value of the number of tens being added.
  • Step 2: Convert this number of tens into a regular number (multiply by 10).
  • Step 3: Add this value to the original number.

Now, let's work through each step:

Step 1: We need to add 2 tens to the number. So, first, we identify that 2 tens is essentially adding 20 (since 10 times 2 equals 20).

Step 2: The original number given is 5254. Now, we convert the 2 tens to a whole number: 2×10=202 \times 10 = 20.

Step 3: Adding the value from Step 2 to 5254 results in:
5254+20=5274 5254 + 20 = 5274 .

Therefore, the number you obtain when you add 2 tens to 5254 is 5274 5274 .

Key Points to Remember

Essential concepts to master this topic
  • Rule: Adding tens means adding to the tens place only
  • Technique: Convert 2 tens to 20, then 5254 + 20 = 5274
  • Check: Count the tens place: 5 + 2 = 7, so 5274 is correct ✓

Common Mistakes

Avoid these frequent errors
  • Adding to the wrong place value position
    Don't add 2 directly to any digit in 5254 = 5256 or 7254! This ignores place value completely. Always convert tens to their actual value (2 tens = 20) and add normally.

FAQ

Everything you need to know about this question

What does '2 tens' actually mean?

+

2 tens means 2 groups of 10, which equals 2×10=20 2 \times 10 = 20 . Think of it like having 2 ten-dollar bills - that's $20 total!

Why can't I just add 2 to the tens place?

+

The tens place already has a 5, so you'd be changing 5254 to 5274. But we need to add 20 to the whole number, not replace a digit. Always add the complete value!

How do I know which digit is the tens place?

+

Count from right to left: ones, tens, hundreds, thousands. In 5254, the tens place is the second digit from the right, which is 5.

What if I need to add hundreds or thousands?

+

Same process! Convert to the actual value first:

  • 3 hundreds = 3×100=300 3 \times 100 = 300
  • 4 thousands = 4×1000=4000 4 \times 1000 = 4000
Then add normally.

Is there a shortcut for adding tens?

+

Yes! Since adding 20 only affects the tens place, you can just add 2 to the tens digit: 5254 → 5274. But make sure you understand why this works first!
