Work: Calculate the value of equation 400/(1+0.12)+200/(1+0.12)^(2)+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400 .
Question type: Mathematical calculation
Solution:
400/(1+0.12)+200/(1+0.12)^(2)+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400
=400/1.12+200/(1+0.12)^(2)+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400
=400/1.12+200/1.12^(2)+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400
=400/1.12+200/1.12^2+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400
=400/1.12+200/1.12^2+200/1.12^(3)-400/(1+0.12)^(4)-400
=400/1.12+200/1.12^2+200/1.12^3-400/(1+0.12)^(4)-400
=400/1.12+200/1.12^2+200/1.12^3-400/1.12^(4)-400
=400/1.12+200/1.12^2+200/1.12^3-400/1.12^4-400
=400/1.12+200/1.2544+200/1.12^3-400/1.12^4-400
=400/1.12+200/1.2544+200/1.404928-400/1.12^4-400
=400/1.12+200/1.2544+200/1.404928-400/1.573519360000001-400
=357.142857+200/1.2544+200/1.404928-400/1.573519360000001-400
=357.142857+159.438776+200/1.404928-400/1.573519360000001-400
=357.142857+159.438776+142.35605-400/1.573519360000001-400
=357.142857+159.438776+142.35605-254.207231-400
=516.581633+142.35605-254.207231-400
=658.937683-254.207231-400
=404.730452-400
=4.730452
Answer:400/(1+0.12)+200/(1+0.12)^(2)+200/(1+0.12)^(3)-400/(1+0.12)^(4)-400=4.730452
