Question

478 . 615 - 314 678+ 385 . 478 - 314 . 322

Answer 1

\(478.615-314.678+385.478-314.322\)

\(=478.\left(615+385\right)-314.\left(678+322\right)\)

\(=478.1000-314.1000\)

\(=478000-314000\)

\(=164000\)

Answer 2

\(478.615-314.678+385.478-314.322\)

\(=478.615+\left(-314\right).678+385.478+\left(-314\right).322\)

\(=478.\left(615+385\right)+\left(-314\right).\left(678+322\right)\)

\(=478.1000+\left(-314\right).1000\)

\(=478000+\left(-314000\right)\)

\(=164000\)
