Question

$$-7+4; -170+170; \pm60+(-160); G+(-3); -4+(-5); 5+(-2)$$

Answer

-7+4;-170+170;p*l*u*s/m*IM*n*u*s*60-160;G-3;-4-5;5-2

Solution


Remove parentheses.
\[\begin{aligned}&-7+4\\&-170+170\\&plu\times \frac{s}{m}\imath nus\times 60+-160\\&G+-3\\&-4+-5\\&5+-2\end{aligned}\]
Simplify.
\[\begin{aligned}&-7+4\\&-170+170\\&plu\times \frac{s}{m}\imath nus\times 60-160\\&G-3\\&-4-5\\&5-2\end{aligned}\]
