 Hi kids! Today let's study subtraction of two digit numbers. Let's try to do an example. There are 45 pupils in the class. If 32 of them are present, how many are absent? The given numbers are 45 pupils in class and 32 pupils present in class. The question is, how many are absent? So we need to subtract 32 from 45. First we need to do the ones column. 5 minus 2 equals 3, right? Then we do the tens. 4 minus 3 equals 1, right? 13 is the difference. 45 minus 32 is 13. So our answer is, 13 pupils are absent. Now let's try to do some drills. Are you ready? 25 minus 12. 13, right? 58 minus 34. 24, correct. 17 minus 20. 50, right? 47 minus 37. 52 minus 10. 42, right? Good job kids! Now it's time to do the drills in your book on subtraction with two digit numbers.
