Answer:

Step-by-step explanation:

Hi,

To solve the given problems we use

brackets.

1) 7 ( 8 - 3 ) = 7 × ( 8 ) + 7 × ( -3 )

= 56 - 21

= 35

2) ( 7 + 2 ) ( 10 - 3 )

= 7 ( 10 - 3 ) + 2 ( 10 - 3 )

Using distributive property

= 7 × ( 7 ) + 2 × ( 7 )

= 49 + 14

= 63

I hope this will useful to you.
