This is solved by breaking the equasion down.
2 { 5 [12 + 5 (500 - 100) + 399 ]}
2 { 5 [12 + 5 (400) + 399]}
2 { 5 [12 + 2000 + 399]}
2 { 5 [2411]}
2 {12055}
24110

2(5(12+5(500−100)+399))
=2(5(12+(5)(400)+399))
=2(5(12+2000+399))
=2(5(2012+399))
=2(5)(2411)
=(2)(12055)
=24110
=2(5(12+(5)(400)+399))
=2(5(12+2000+399))
=2(5(2012+399))
=2(5)(2411)
