• Just remember kids if somebody walks up to you on the street and they ask you a math problem answer it. :)
• Uhm well i guess your right
• 1.2, 12/10 or call it 1 2/10. Are these still same?
• Yes, 1.2, 12/10, and 1 2/10 are all equal.

Have a blessed, wonderful day!
• wait when you add 9 and the 3 won't the 12 be in the hundredths place rather than the ones place?
• for the tenths place, there is only 1 digit after the dot, so if it is 12, the 2 would remain in the tenths place and the 1 would be carry over to the ones place.
• how do you know the answer? like for 0.8 and 0.1
• the awnser is 0.9
• The places change the bigger the number which gets confusing anybody know a trick?

Make sure to line up the decimal points first! If there are any missing digits, then write 0’s for them.

Then add like you would with whole numbers. In the answer, put the decimal point directly underneath the lined-up decimal points.

Have a blessed, wonderful day!
• who does not know what 0.8 and 0.1 is tho
• thank you for helping me👍
• At the beginning of this video I already knew what the answer was but I still listened to Sal tell us doing the problem on his own. I personally think that decimals are kinda easy now. What did all of you guys think about this video though? I personally enjoyed every part of it.
• boi i dont get it m a bannana oof
• I’m going to try to show you how to do it.

0.1
+0.8

0.9

It’s like normal adding, but you bring down the decimal point.
