Remove parentheses

Theory

Remove parentheses

Sometimes, parentheses are added in a mathematical expression solely for clarity, but for the sake of correctness they could just as easily be removed. A few examples are as follows. 4+(52)=4+52(43)8=438 \begin{aligned} 4+(5-2)&=4+5-2\\[0.7em] (4\cdot3)\cdot 8 &= 4\cdot3 \cdot8 \end{aligned}
