6(7+5)+3+75 ;

Answered by catarinanguyen2007 | 2024-06-12

Using the numbers 7, 5, 6, and 3, we can arrange them to equal 75 with the expression 6 × ( 7 + 5 ) + 3 . By evaluating this step-by-step, we get 75 as the result. This demonstrates how careful selection of operations and parentheses can lead to achieving the target number.
