Given:
The basic mathematical operators(brackets, addition, substraction and division)
To find:
Use the digit 4 four times and apply the basic mathematical operators(brackets,addition,substraction and division) to get 7 as your answer.
Solution:
From given, we have,
The basic mathematical operators(brackets, addition, subtraction and division)
Here we use the trial and error method to find the digit.
Consider the number 4.
4 + 4 - (4 ÷ 4)
we use the BODMAS rule to solve this problem.
(B - brackets , O - off , D - division , M - multiplication , A - addition, S - subtraction )
= 4 + 4 - 1
= 7
Thus, 4 is the required digit
