# Estimate using front-end estimation with ...

Estimate using front-end estimation with adjustment: 29.92 + 39.03 = ?
Hi there!

29.92 + 39.03 = ?

Let's estimate it with the first digits only:
20.00 + 30.00 = 50.00

Add 9.92 + 9.03, which is like 10.00 + 10.00 = 20.00

Add that to the 50, giving:
70.00

Let me know if you have any questions. If not, thanks for pressing "Accept".

What if the question says - Estimate using front-end digits. Would I get the same answer?
No, you would not get the same answer. The adjustment is crucial to get the answer of 70.

If you only use the front end digits:

29.92 + 39.03 = ?

Let's estimate it with the first digits only:
20.00 + 30.00 = 50.00

50.00

Lets take 29.92 + 39.03 = ?
Estimate using front-end digits with adjustment? Would we get 70?
Yes, if you use adjustment, that's the first answer I gave: 70.
If you don't have adjustment, that's the second answer I gave: 50.

I want to make sure you completely understand this, so let me know if you have any other questions before you press "Accept". Thanks!

Ok, let's make sure I understand -
If I have 59.62 + 89.22 = ?
Using front-end digits and an adjustment, I would get ?
