Maths

L.I I am learning to add three or more numbers by first making pairs that add up to a tens number.

4 + 8 + 36 = 48

How I got the answer was Like this: 36 + 4 = 40 + 8 = 48

65 + 3 + 5 = 73

How I got the answer was Like this: 65 + 5 = 70 + 3 = 73

24 + 6 + 3 + 2 = 35

How I got the answer was Like this: 24 + 6 = 30 + 3 + 2 = 5  + 30 = 35

16 + 2 + 8 + 4 = 30

How I got the answer was Like this: 16 + 4 = 20 + 2 + 8 = 10 + 20 = 30

56 + 9 + 4  + 1 = 70

How I got the answer was Like this: 56 + 4 = 60 + 9 + 1 = 10+ 60 = 70

44 + 2 + 8 + 6 = 60

How I got the answer was Like this: 44 + 6 = 50 + 2 + 8 = 10 + 50 = 60

58 + 2 + 5 + 4 + 5 = 74

4 + 6 + 9 + 2 +  61 = 82

How I got the answer was Like this: 4 + 6 = 10 + 61 + 9 = 70 + 10 = 80 + 2 = 82

72 + 4 + 8 = 84
