Although this is a simple question but I cannot think of which operations to put in to make this expression correct.

7 ___ (7 ___ 7) ____ 7 = 5

Please help, somebody. Confused

Hey Quang Anh,

Following is the solution:

7 - (7 + 7) ÷ 7
= 7 - (14 ÷ 7)
= 7 - 2
= 5

========

Trust this helps.

Do let me know again if there's further clarification.

Cheers,
Edward
