Question

(2+4+6+...+1001).(35.444-140.111)

Answer 1

\(\left(2+4+6+...+1001\right)\left(35.444-140.111\right)=\left(2+4+6+...+1001\right)\left[111\left(35.4-140\right)\right]=\left(2+4+6+...+1001\right).0=0\)

Answer 2

\(\left(2+4+6+...+1001\right)\cdot\left(35\cdot444-140\cdot111\right)\)

\(=\left(2+4+6+...+1001\right)\cdot\left[35\cdot111\left(4-4\right)\right]\)

=0
