Eights Are Redundant

Logic Level 1

Using only addition, subtraction, multiplication, division and parentheses operations, can we make the following equation true:

8 8 8 8 8 = 32 \Large 8 \ \ 8 \ \ 8 \ \ 8 \ \ 8 \ \ = \ \ 32

Note : Combining the digits is not allowed. For example, you can't merge 8 and 8 to get 88.

Haha , I made it almostsimilar but in an inverse way.

Namely (8+8)/8 * (8+8) = 2* 16 = 32 anyway.

( 8 × 8 × 8 ) ÷ ( 8 + 8 ) (8\times8\times8) ÷ (8 + 8)\\
( 512 ) ÷ ( 16 ) = (512) ÷ (16) = 32 32
