You can make 10 using four 2s by applying arithmetic operations. One way to do this is: ( (2 + 2) \times (2 + 2) = 4 \times 4 = 16 ), which is incorrect. However, you can also achieve 10 by using the equation: ( 2 \times 2 + 2 + 2 = 10 ).
44 divided by 4.4 or (44 - 4) divided by 4
(44 - 4) / 4
9 + (9/9) = 10
9
(10 + 10 + 10) / 10 = 30 / 10 = 3 / 1 = 3
(44 - 4)/4
44 divided by 4.4 or (44 - 4) divided by 4
(44 - 4) / 4
3*3 + 3/3 = 10
9 + (9/9) = 10
9

7/.7 x 7/.7 = 10 x 10 = 100
4/.4 + 4/4 [= 10+1 = 11]
(10 + 10 + 10) / 10 = 30 / 10 = 3 / 1 = 3
