Salut !

3 × ( - 98 + 2 ) + 3 × 98 = 3 × ( - 96 ) + 3 × 98 = 3 × ( - 96 + 98 ) = 3 × 2 = 6

( - 25 ) × ( 45 - 100 ) + 25 × 45 = ( - 25 ) × ( - 55 ) + 25 × 45 = 25 × 55 + 25 × 45 = 25 × ( 55 + 45 ) = 25 × 100 = 2500

( - 15 ) × ( - 7 + 15 ) - 7 × 15 = - 15 × 8 - 7 × 15 = 15 × ( - 8 - 7 ) = 15 × ( - 15 )

= - 255

( - 1 ) × ( 35 - 88 ) = ( - 1 ) × ( - 53 ) = 53

( - 1 ) × ( - 28 - 112 ) = ( - 1 ) × ( - 140 ) = 140

( 25 - 62 - 38 ) × ( - 4 ) = - 75 × ( - 4 ) = 300

8 × ( - 8 + 100 - 22 + 25 ) = 8 × 95 = 760
