1.) 13 × ( 140 ÷ (-7)) + (-2) × 15

= 13 × -( 140 ÷ 7 ) + (-2) × 15

= 13 × (-20) + (-2) × 15

= -( 13 × 20 ) + (-2) × 15

= (-260) + (-2) × 15

= (-260) + -( 2 × 15 )

= (-260) + (-30)

= -( 260 + 30 )

= (-290)

2.) 412 ÷ 4 + 104 × 9

= ( 412 ÷ 4 ) + 104 × 9

= 103 + 104 × 9

= 103 + ( 104 × 9 )

= 103 + 936

= 1.039
