$- 8.2 + 6 \cdot (5 - 7) = - 20.2$ $-8.2+6*(5-7)=-20.2$

Explanation:

PEMDAS stands for order of operations i.e. parentheses, then exponents, then multiplication and division and finaly addition and subtraction.

Hence $- 8.2 + 6 \cdot (5 - 7)$ $-8.2+6*(5-7)$

= $- 8.2 + 6 \cdot (- 2)$ $-8.2+6*(-2)$ $\to$ $->$ simplifying parentheses

= $- 8.2 + (- 12)$ $-8.2+(-12)$ $\to$ $->$ doing multiplication

= $- 8.2 - 12$ $-8.2-12$

= $- 20.2$ $-20.2$
