[Phạm Trà Giang]

1.seventy five - thirty seven = 75 - 37 = 38

2.thirteen + seven = 13 + 7 = 20

3.six x nine = 6 x 9 = 36

4.sixty five + fourteen = 65 + 14 = 79

5.twelve x five = 12 x 5 = 60

6.eighty - twelventy three = 80 - 23 = 57

7.fourty five + nine = 45 + 9 = 54

8.ninety six - fifty two = 96 - 52 = 44

9.sixty nine : three = 69 : 3 = 23

10.thirty fine + nine= 35 + 9 = 44
