00:00hi kids today we will learn subtraction with two-digit numbers here are 15 stars
00:13on the board and if I erase four stars how many stars will be left let me help
00:24you calculate write the bigger number first that is 15 1 is in the tens place
00:385 is in the units place or ones place now write the other number that is 4 4
00:53is in one's place or units place so write it below 5 good now you have to
01:08subtract 4 from 15 first of all subtract 4 from 5 5 minus 4 you get 1 so write 1
01:27one's place in the sum now there is nothing to subtract from 1 so write 1 at the tens place
01:41so we got to know 15 minus 4 you get 11 so 11 stars will be left good kids now you know how
02:02to write numbers to subtract them let's take another example here are 24 smileys on the board
02:14and if I remove 12 smileys how many smileys will be left let me help you calculate write the bigger
02:29number first that is 24 2 is in the tens place 4 is in the units place or ones place now take
02:46the other number that is 12 write 12 as 2 is in the ones place digit so write it below 4 1 is in
03:04the tens place digit so write it below 2 good now subtract 2 from 4 you get 2 so write 2 at
03:21the one place now subtract 1 from 2 you get 1 and write it at the tens place good so we got 24
03:41minus 12 equals 12 so 12 smileys will be left good now you know how to do subtraction with
03:59two-digit numbers but you need practice now you may go ahead and take a quiz to learn more bye
