=-26.31+48.14-6.465-0.5×20.41×1.45×0.033333-1/2×12.93×0.2025
=-26.31+48.14-6.465-10.205×1.45×0.033333-1/2×12.93×0.2025
=-26.31+48.14-6.465-14.79725×0.033333-1/2×12.93×0.2025
=-26.31+48.14-6.465-0.493237-1/2×12.93×0.2025
=-26.31+48.14-6.465-0.493237-0.5×12.93×0.2025
=-26.31+48.14-6.465-0.493237-6.465×0.2025
=-26.31+48.14-6.465-0.493237-1.309163
=21.83-6.465-0.493237-1.309163
=15.365-0.493237-1.309163
=14.871763-1.309163
=13.5626
Answer:-26.31+48.14×1-1/2×12.93×1^2-1/2×20.41×1.45×(1-2/3×1.45)-1/2×12.93×(1-1.45)^2=13.5626
