Evaluating this expression is a matter of being especially attentive to the order of operations:

 $$-23.6+(-4.8)+(4+4/5)*0.4-(-11.5)$$ This is the original expression. Let's clean it up a bit, shall we? $$-23.6-4.8+4\frac{4}{5}*0.4+11.5$$ According to order of operations, do $$4\frac{4}{5}*0.4$$ first. We have to convert to an improper fraction $$-23.6-4.8+\frac{24}{5}*\frac{2}{5}+11.5$$ Multiply the fractions together $$-23.6-4.8+\frac{48}{25}+11.5$$ Convert $$\frac{48}{25}$$to a decimal. $$-23.6-4.8+1.92+11.5$$ Do the calculations from left to right now because addition and subtraction have equal priority $$-28.4+1.92+11.5$$ $$-26.48+11.5$$ $$-14.98$$ This is your answer
