Arrow-Puffin-1_Semester-1 Maths 125PROPERTIES OF SUBTRACTION%u2022 When we subtract 1 from any number, we get the number just before the given number. Example : There are 5 mangoes and 1 is eaten. How many are left? 5 %u2014 1 = 4 (4 comes before 5).%u2022 When we subtract zero from a number, we get the same number from which 0 is subtracted. Example :There are 3 apples. None is eaten. How many are left? None is eaten. So 3 apples are left. 3 %u2014 0 = 3.%u2022 When we subtract a number from itself, we always get a zero.Example : There are 2 pastries. Raju eats 2. How many pastries are left?None (nothing) is left as 2 out of 2 pastries are eaten.2 %u2014 2 = 0.SUBTRACTION ON NUMBER LINEMona had 8 sweets. She gave 3 sweets to her friend. How many sweets are left with Mona?Start at 8. Then take 3 steps back. You will reach 5.So, 8 %u2014 3 = 5 0 1 2 3 4 5 6 7 8 9 10Let's Understand Conceptual UnderstandingLet's Understand Conceptual Understanding
