# Worksheet to Find the Sum using Addition Property

Practice the questions provided in the worksheet to find the sum using addition property. Using the mathematical property involving addition to rewrite the statement and find the sum.

1. Fill in the blanks:

(i) 11 + 9 = 9 + ………..

(ii) 63 + 27 = 27 + ………..

(iii) ……….. + 37 = 37 + 41

(iv) 125 + ……….. = 128 + 125

(v) 48 + 0 = ………..

(vi) 0 + ……….. = 98

2. What is the sum if zero is added to 101?

3. Find the sum of 53 + 47 and 47 + 53. On this basis give the property of addition.

4. Fill up the gaps with the proper numbers:

(i) (101 + 99) + 200 = (99 + 200) + ……….. = (101 + 200) + ………..

(ii) 103 + (224 + 155) = (103 + 224) + ……….. = (155 + 224) + ………..

5. Give three examples for the property of addition which states that the grouping does not change the sum of three numbers.

(i) 48 + 31 =

(ii) 9 + 11 =

(iii) 127 + 251 =

7. Find the sum of:

(i) 9 + 5 + 6 =

(i) 76 + 67 =

(ii) 9 + 99 =

(iii) 318 + 426 =

(iv) 98 + 73 =

(v) 73 + 89 =

(vi) 239 + 328 =

(vii) 28 + 34 + 56 =

(viii) 39 + 49 + 59 =

(ix) 180 + 810 + 0 =

(x) 10 + 50 + 70 =

(xi) 93 + 94 + 95 =

(xii) 247 + 275 + 308 =

9. Find the sum of 372, 162 and 378.
