Question

How do you make 7,5,6,and 3 equal 75 without parentheses

Answer 1

5 times 6 time 7 divided by 3 plus 5

Answer 2

`(6 * 5)/(3) * 7 +5`

Explanation:

To express this problem using 7, 5, 6 and 3 without parenthesis, we have to use at least one number twice, because suing parenthesis is so much easier to express the result. So, the operations would be:

`(6 * 5)/(3) * 7 +5=(30)/(3)* 7 +5\\ 10* 7 +5=70+5=75`

Therefore, the expression would be:

`(6 * 5)/(3) * 7 +5`
