Question

4 2 7 1 4 =18 starting on the left,use each symbol once to get to the answer + - × ÷ ​?

​

Answer 1

• Given :- 4 2 7 1 4 =18

• To find:- How 4 2 7 1 4 =18 is formed by using + - × ÷ symbols once

• Solution:- According to the question, we have to use + - × ÷ symbols to form 18 from left side.

so, 4 - 2 = 2 (so,we can't use '-' again)

then 2× 7 = 14 ( so, we can't use '×' again)

then 14 ÷ 1 = 14 ( so, can't use '÷' again)

and then 14+4 = 18 ( and now all symbols used once and make 18)

So the final answer is [{(4-2)×7} ÷ 1]+4 = 18
