Use order of operations (PEMDAS) <span>83-<span>(<span>59-<span>(<span>22-18</span>)</span></span>) </span></span><span><span>83-<span>(<span>59-4</span>) </span></span></span><span><span>83-55=</span></span>28
The value of the equation is 28 because you would do the parenthesis in the brackets first which is 22-18 then you would subtract 59-4. Lastly you would subtract 83-55 which will give you 28
