19,5+19,5+19,5+19,5x7-19,5:0,1

Answer 1

19,5 + 19,5 + 19,5 + 19,5 x 7 - 19,5 : 0,1

= 19,5 + 19,5 + 19,5 + 19,5 x 7 - 19,5 x 10

= 19,5 x (1 + 1 + 1 + 7 - 10)

= 19,5 x 0

= 0

Answer 2

19,5 + 19,5 + 19,5 + 19,5 x 7 - 19,5 : 0,1

= 19,5 x 1 + 19,5 x 1  + 19,5 x 1  + 19,5 x 7 - 19,5 x 10

= 19,5 x (1 + 1 + 1 + 7 - 10)

= 19,5 x (10 - 10)

= 19,5 x 0

= 0

Answer 3

\(19,5+19,5+19,5+19,5.7-19,5:0,1\)

\(=19,5+19,5+19,5+19,5.7-19,5.10\)

\(=19,5.1+19,5.1+19,5.1+19,5.7-19,5:\)

\(=19,5.\left(1+1+1+7-10\right)\)

\(=19,5.0\)

\(=0\)

Answer 4

\(19,5+19,5+19,5.7-19,5:0,1\)

\(=19,5+19,5+19,5+19,5.7-19,5.10\)

\(=19,5.\left(1+1+1+7-10\right)\)

\(=19,5.0\)

\(=0\)
