Verify (–45) × [10 + (–3)] = [(–45) × 10] + [(–45) × (–3)]
samaradavis:
The first step we have to do is to open the brackets = -45×10-3= -45 × 10 - 45 × -3. Now the next step is that we have to multiply all the multiplication terms up = -45 × 7 = -450 - 135. Then the next step is = -385 = -585 therefore your answer is -385 = -585
Sorry i did another method
my answer is wrong
ok
any question???????????????????????????????????????????????/

LHS = (–45) × [10 + (–3)]
= (–45) × [10 –3]
= (–45) × 7
= -315
RHS = [(–45) × 10] + [(–45) × (–3)]
= (–450)+ [(–45) × (–3)]
= (–450)+ 135
= -315
LHS = RHS (Proved)
= (–45) × [10 –3]
= (–45) × 7
= -315
RHS = [(–45) × 10] + [(–45) × (–3)]
= (–450)+ [(–45) × (–3)]
= (–450)+ 135
= -315
LHS = RHS (Proved)

L.H.S
( -45 )× { 10 + (-3) }
= -45 × (7)
= -315
R.H.S
{ (-45 ) ×10} + ( -45 ) × (-3)}
= -450 +135
= -315
L.H.S = R.H.S
hence proved.
