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

Answer:

$\frac{6 \times 5}{3} \times 7 +5$

Step-by-step 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:

$\frac{6 \times 5}{3} \times 7 +5=\frac{30}{3}\times 7 +5\\ 10\times 7 +5=70+5=75$

Therefore, the expression would be:

$\frac{6 \times 5}{3} \times 7 +5$
