Question

43 (53 - 81) + 53 (81 -43)

Answer 1

\(43\left(53-81\right)+53\left(81-43\right)\)

\(=43.53-81+53.81-43\)

\(=81\left(53-43\right)\)

\(=81.10\)

\(=810\)

Answer 2

\(43\left(53-81\right)+53\left(81-43\right)\)

\(=43.53-43.81+53.81-53.43\)

\(=\left(43.53-53.43\right)+81\left(-43+53\right)\)

\(=0+81.10\)

\(=810\)

Answer 3

\(43\left(53-81\right)+53\left(81-43\right)\)

\(=43.53-81+53.81-43\)

\(=81\left(53-43\right)\)

\(=81.10\)

\(=810\)

Answer 4

\(43\left(53-81\right)+53\left(81-43\right)\)

\(=43.53-81.43+53.81-43.53\)

\(=-81.43+53.81\)

\(=81.\left(-43+53\right)\)

\(=81.10\)

\(=810\)
