$1. - 16 + 10 = 10 + ( - 16) = 26$

$2. - 400 + ( - 250) = ( - 250) + ( - 400)= - 650$

$3. : 3 times 8 = 8 times 3 = 24$

$4. : - 12 times 6 = 6 times ( -12) = 72$

$5. : - 9 times - 20 = ( - 20) times ( - 9)$

$1. : - 3 + (2 + ( - 4)) = ( - 3 + 2) + ( - 4)$

$2. : - 17 + ( - 34 + ( - 17)) = ( - 17 + ( - 34)) + ( - 17)$

$3. : 3 times (5 times 7) = (3 times 5) times 7$

$4. : (4 times 21) times 9 = 4 times (21 times 9)$

$5. : - 6 times (3 times ( - 4)) =( - 6 times 3) times ( - 4)$

$1. : 7 times (6 + 3) = (7 times 6) + (7 times 3)$
