Question
Name the property that justifies each step.
[(2x100)+(3x10)]+[(1x100)+(5x10)]
= (2x100)=[(3x10)+(1x100)]+(5x10) I think this is Commutative
= (2x100)+[(1x100)+(3x10)]+(5x10) I think this is Distributive property
=[(2x100)+(1x100)]+[(3x10)+(5x10)] I think that this is Associative property.
=[(2+1)x100]+[(3+5)x10] I think that this is the Distributive property.
= (3x100)+(8x10) This is Basic facts.
=380 Expanded form to standard form.
Is this all correct? Thanks for your help.
