Answer 1

79x54+54x38-18x3

= 79x54+54x38-54

=54x(79+38-1)

=54x116

=6264

Answer 2

79 x 54 + 54 x 38 - 18 x 3

= 79 x 54 + 38 x 54 - 54 x 1

= ( 79 + 38 - 1 ) x 54 

= 116 x 54

= 16 + 100 x 54

= 16 + 5400

= 5416

Answer 3

\(79\cdot54+54\cdot38-18\cdot3\)

\(=79\cdot54+54\cdot38-54\cdot1\)

\(=54\cdot\left(79+38-1\right)\)

\(=54\cdot116\)

\(=6264\)

Answer 4

79 x 54 + 54 x 38 - 18 x 3

= 79 x 54 + 38 x 54 - 54 x 1

= ( 79 + 38 - 1 ) x 54

= 116 x 54

= 16 + 100 x 54

= 16+ 5400

= 5416

Answer 5

79 x 54 + 54 x 38 - 18 x 3

= 79 x 54 + 38 x 54 - 54 x 1

= ( 79 + 38 - 1 ) x 54

= 116 x 54

= 16 + 100 x 54

= 16+ 5400

= 5416

Answer 6

79 * 54 + 54 * 38 - 18 * 3 

= (79 + 38 ) * 54 - 18 * 3

= 117 * 54 - 54

= 117 * 54 - 54 * 1

= ( 117- 1 ) * 54

= 116 * 54

= 6264

Answer 7

79 x 54 + 54 x 38 - 18 x 3

= 79 x 54 + 38 x 54 - 54 x 1

= ( 79 + 38 - 1 ) x 54

= 116 x 54

= 16 x 54 + 100 x 54

=  + 5400
