g) (+5) × (-99) × 13 × 0

Answer 1

a)(-7) x (-8) x (-10)= -560

b)(+9) x 0 x (-7)= 0

c)(-2) x (-18) x (-1)= -36

d)8 x (-9) x (-1)= 72

e)8 x (-6) x (-100)= 4800

f)(-5) x (+2) x (-3)=15

g)(+5) x (-99) x 13 x 0=0

Answer 2

a ) ( -7 ) x ( -8 ) x ( -10 ) =

= - ( 7 x 8 x 10 )

= - ( 56 x 10 )

= - 560

------------------------------------------

b ) ( +9 ) x 0 x ( -7 ) = 0

-------------------------------------------

c ) ( -2 ) x ( -18 ) x ( -1 ) =

= - ( 2 x 18 x 1 )

= - ( 36 x 1 )

= - 36

----------------------------------------

d ) 8 x ( -9 ) x ( -1 ) =

= 8 x 9 x 1

= 72 x 1

= 72

--------------------------------------------

e ) 8 x ( -6 ) x ( -100 ) =

= 8 x 6 x 100

= 48 x 100

= 4800

----------------------------------------

f ) ( -5 ) x ( + 2 ) x ( -3 ) =

= 5 x 2 x 3

= 10 x 3

= 30

--------------------------------------

g ) ( +5 ) x ( -99 ) x 13 x 0 = 0
